(output deratings are relative to the sdram input clock.) for example, if the measured jitter into a ddr2?667 sdram has t err(6-10per).min = ? 272 ps and t err(6- 10per).max = + 293 ps, then t dqsck.min(derated) = t dqsck.min ? t err(6-10per).max = ? 400 ps ? 293 ps = ? 693 ps and t dqsck.max(derated) = t dqsck.max ? t err(6-10per).min = 400 ps + 272 ps = + 672 ps. similarly, t lz.dq for ddr2?667 derates to t lz.dq.min(derated) = - 900 ps ? 293 ps = ? 1193 ps and t lz.dq.max(derated) = 450 ps + 272 ps = + 722 ps. (caution on the min/max usage!) 9) input clock jitter spec parameter. the jitter specified is a random ji tter meeting a gaussian distribution. 10) these parameters are specified per their average values. 11) t cke.min of 3 clocks means cke must be registered on three consecutive po sitive clock edges. cke must rema in at the valid input level t he entire time it takes to achieve the 3 cloc ks of registration. thus, after any cke trans ition, cke may not transition from its v alid level during the time period of t is + 2 x t ck + t ih . 12) dal = wr + ru{ t rp (ns) / t ck (ns)}, where ru stands for round up. wr refers to the twr parameter stored in the mrs. for t rp , if the result of the division is not already an integer, round up to the next highest integer. t ck refers to the application clock period. example: for ddr2?533 at t ck = 3.75 ns with t wr programmed to 4 clocks. t dal = 4 + (15 ns / 3.75 ns) clocks = 4 + (4) clocks = 8 clocks. 13) t dal.nck = wr [nck] + t nrp.nck = wr + ru{ t rp [ps] / t ck.avg [ps] }, where wr is the value programmed in the emr. 14) input waveform timing t dh with differential data strobe enabled mr[bit10] = 0, is refe renced from the differential data strobe crosspoint to the input signal crossing at the v ih.dc level for a falling signal and from the differential data strobe crosspoint to the input signal crossing at the v il.dc level for a rising signal applied to the device under test. dqs, dqs signals must be monotonic between v il.dc.max and v ih.dc.min . see figure 3 . 15) t dqsq : consists of data pin skew and output pattern effects, and p-c hannel to n-channel variation of the output drivers as well as o utput slew rate mismatch between dqs / dqs and associated dq in any given cycle. 16) these parameters are measured from a data strobe signal ((l/u/r)dqs / dqs ) crossing to its respec tive clock signal (ck / ck ) crossing. the spec values are not affected by t he amount of clock jitter applied (i.e. t jit.per , t jit.cc , etc.), as these are relative to the clock signal crossing. that is, these param eters should be met whether clock jitter is present or not. 17) input waveform timing t ds with differential data strobe enabled mr[bit10] = 0, is re ferenced from the input signal crossing at the v ih.ac level to the differential data strobe crosspoint for a ri sing signal, and from the inpu t signal crossing at the v il.ac level to the differential data strobe crosspoint for a falling signal appli ed to the device under test. dqs, dq s signals must be monotonic between v il(dc)max and v ih(dc)min . see figure 3 . 18) if t ds or t dh is violated, data corruption may occur and the data must be re -written with valid data before a valid read can be executed. 19) these parameters are measured from a data signal ((l/u)dm, (l/u )dq0, (l/u)dq1, etc.) transition edge to its respective data strobe signal ((l/u/r)dqs / dqs ) crossing. 20) t hp is the minimum of the absolute hal f period of the actual input clock. t hp is an input parameter but not an input specification parameter. it is used in conjunction with t qhs to derive the dram output timing t qh . the value to be used for t qh calculation is determined by the following equation; t hp = min ( t ch.abs , t cl.abs ), where, t ch.abs is the minimum of the actual instantaneous clock high time; t cl.abs is the minimum of the actual in stantaneous clock low time. 21) t hz and t lz transitions occur in the same access time as valid data trans itions. these parameters are referenced to a specific voltage lev el which specifies when the device output is no longer driving ( t hz ), or begins driving ( t lz ) . 22) input waveform timing is referenced from the input signal crossing at the v il.dc level for a rising signal and v ih.dc for a falling signal applied to the device under test. see figure 4 . 23) input waveform timing is referenced from the input signal crossing at the v ih.ac level for a rising signal and v il.ac for a falling signal applied to the device under test. see figure 4 . 24) these parameters are measured from a comm and/address signal (cke, cs, ras, cas, we, odt, ba0, a0, a1, etc.) transition edge to its respective clock signal (ck / ck ) crossing. the spec values are not affect ed by the amount of cl ock jitter applied (i.e. t jit.per , t jit.cc , etc.), as the setup and hold are relative to the clock signal crossing that latches the command/address. that is, these paramet ers should be met whether clock jitter is present or not. 25) t qh = t hp ? t qhs , where: t hp is the minimum of the absolute half period of the actual input clock; and t qhs is the specification value under the max column. {the less half-pulse width distortion present, the larger the t qh value is; and the larger the valid data eye will be.} examples: 1) if the system provides t hp of 1315 ps into a ddr2?667 sdram, the dram provides t qh of 975 ps minimum. 2) if the system provides t hp of 1420 ps into a ddr2?667 sdram, the dram provides t qh of 1080 ps minimum. 26) t qhs accounts for: 1) the pulse duration distortion of on-chip clock circuits, which represents how well the actual t hp at the input is transferred to the output; and 2) the worst case push-out of dq s on one transition followed by the worst case pull-in of dq on the next transition, both of which are independent of each other, due to da ta pin skew, output pattern effects, and pchannel to n-channe l variation of the output drivers. 27) the auto-refresh command interval has be reduced to 3.9 s when operating the ddr2 dram in a temperature range between 85 c and 95 c. hys72t[64/128/256]xx0ep?

(output deratings are relative to the sdram input clock.) for example, if the measured jitter into a ddr2?667 sdram has t jit.per.min = ? 72 ps and t jit.per.max = + 93 ps, then t rpre.min(derated) = t rpre.min + t jit.per.min = 0.9 x t ck.avg ? 72 ps = + 2178 ps and t rpre.max(derated) = t rpre.max + t jit.per.max = 1.1 x t ck.avg + 93 ps = + 2843 ps. (caution on the min/max usage!). 33) when the device is operated with i nput clock jitter, this parameter needs to be derated by the actual t jit.duty of the input clock. (output deratings are relative to the sdram input clock.) for ex ample, if the measured jitter into a ddr2?667 sdram has t jit.duty.min = ? 72 ps and t jit.duty.max = + 93 ps, then t rpst.min(derated) = t rpst.min + t jit.duty.min = 0.4 x t ck.avg ? 72 ps = + 928 ps and t rpst.max(derated) = t rpst.max + t jit.duty.max = 0.6 x t ck.avg + 93 ps = + 1592 ps. (caution on the min/max usage!). 34) for these parameters, the ddr2 sdram device is characterized and verified to support t nparam = ru{ t param / t ck.avg }, which is in clock cycles, assuming all input cl ock jitter specifications are satisfied. for example, the device will support t nrp = ru{ t rp / t ck.avg }, which is in clock cycles, if all input clock jitter specifications are met. this means: for ddr2?667 5?5?5, of which t rp = 15 ns, the device will support t nrp = ru{ t rp / t ck.avg } = 5, i.e. as long as the input cloc k jitter specifications are met, prechar ge command at tm and active command at tm + 5 is valid even if (tm + 5 - tm) is less than 15 ns due to input clock jitter. 35) t wtr is at lease two clocks (2 x t ck ) independent of operation frequency. 36) this timing parameter is relaxed than industry standard hys72t[64/128/256]xx0ep?
