data book 1 3.00 hys 72vx2xxgr pc100 registered sdram-modules 3.3 v 168-pin registered sdram modules 64 mb, 128 mb, 256 mb, 512 mb & 1 gb densities the hys 72vx2x0gr family are industry standard 168-pin 8-byte dual in-line memory modules (dimms) which are organized as 8m 72, 16m 72, 32m 72, 64m 72 & 128m 72 high speed memory arrays designed with synchronous drams (sdrams) for ecc applications. the 32m x 72 (256mbyte) registered dimm module is available in two versions (12 or 13 row addresses). all control and address signals are registered on-dimm and the design incorporates a pll circuit for the clock inputs. use of an on-board register reduces capacitive loading on the input signals but are delayed by one cycle in arriving at the sdram devices. decoupling capacitors are mounted on the pc board. the dimms use a serial presence detects scheme implemented via a serial e 2 prom using the 2-pin i 2 c protocol. the first 128 bytes are utilized by the dimm manufacturer and the second 128 bytes are available to the end user. all infineon 168-pin dimms provide a high performance, flexible 8-byte interface in a 133.35 mm long footprint. ? 168-pin jedec standard, registered 8 byte dual-in-line sdram module for pc and server main memory applications ? one bank 8m 72, 16m 72, 32m 72 and 64m 72 organization, two bank 128m 72 organization ? optimized for ecc applications with very low input capacitances ? programmed latencies: ? single + 3.3 v ( 0.3 v) power supply ? programmable cas latency, burst length, and wrap sequence (sequential & interleave) ? auto refresh (cbr) and self refresh ? all inputs and outputs are lvttl compatible ? serial presence detect with e 2 prom ? utilizes sdrams in tsopii-54 packages with registers and pll. the two bank module uses stacked tsop54 packages. ? card size: 133.35 mm 38.1 mm/ 43.18 mm 4,00/6.50 mm with gold contact pads ? this specification follows intels pc sdram registered dimm specification rev. 1.2 product speed cl t rcd t rp -8 pc100 2 2 2 -8a pc100 3 2 2 ? performance: -8 -8a unit pc100 pc100 f ck clock frequency (max.) 100 100 mhz t ck clock cycle time (min.) 10 10 ns t ac clock access time (min.) 6 6 ns

hys 72vx2xxgr pc100 registered sdram-modules data book 13 3.00 notes 1. the registered dimm modules are designed to operate under system operating conditions between 0-55 deg c ambient, 500 mb/sec sustained bandwidth and 0 lfm airflow. 2. these parameters depend on the cycle rate. all values are measured at 100 mhz operation frequency. input signals are changed once during tck excepts for icc6 and for standby currents when tck = infinity. 3. these parameters are measured with continous data stream during read access and all dq toggling. cl=3 and bl=4 is assumed and the vcc current is excluded. 4. an initial pause of 100 m s is required after power-up. then a precharge all banks command must be given followed by eight auto refresh (cbr) cycles before the mode register set operation can begin. also the on-dimm pll must be given enough clock cycles to stabilize before any operation can be guaranteed. 5. ac timing tests have v il = 0.8 v and v ih = 2.0 v with the timing referenced to the 1.4 v crossover point. the transition time is measured between v ih and v il . all ac measurements assume t t = 1 ns with the ac output load circuit shown. specified t ac and t oh parameters are measured with a 50 pf only, without any resistive termination and with a input signal of 1 v/ns edge rate between 0.8 v and 2.0 v. 6. self refresh exit is a synchronous operation and begins on the second positive clock edge after cke returns high. self refresh exit is not complete until a time period equal to t rc is satisfied after the self refresh exit command is registered. 7. referenced to the time at which the output achieves the open circuit condition, not to output voltage levels. 8. due to the usage of a register device on all input and address signals, all external command cycle are delayed by one clock (reg-dimm latency = 1) on the module board. 9. delayed by one clock cycle due to the use of the register device. a serial presence detect storage device - e 2 prom 34c02 - is assembled onto the module. information about the module configuration, speed, etc. is written into the e 2 prom device during module production using a serial presence detect protocol (i 2 c synchronous 2-wire bus) 50 pf i/o measurement conditions for t ac and t oh spt03404 clock 2.4 v 0.4 v input hold t setup t t t output 1.4 v t lz ac t t ac oh t hz t 1.4 v cl t ch t

hys 72vx2xxgr pc100 registered sdram-modules data book 21 3.00 functional description all 168-pin registered dimms conform to a compatible set of timing and operation characteristics intended to comply with the 100 mhz standards. the registered dimms achieve high speed data transfer rate up to 100 mhz. all control and address signals are synchronized with the positive edge of externally supplied clocks and are registered on-dimm and hence delayed by one clock cycle in arriving at the sdram devices. the use of the on-board register reduces the capacitive loading of the dimm on input control and address signals. the sdram device data lines (dq) are connected directly to the dimm tabs through 10 ohm series resistors. all the following timing diagrams and explanations show dimm operation at the tabs, not sdram operation. the picture below depicts an overview of the effect of the registered mode on the data outputs (dqs) for a read operation. without the registers, the data is delayed according to the device cas latency, in the case two clocks. with the register, the data is delayed according to the device cas latency plus an additional clock cycle. this is know as the dimm cas latency, and in this example is four three. the data path can be thought of as a pipeline in which the register effectively lengthens the pipe by one clock cycle. in case of a burst write command the data-in is delayed one clock due the op-dimm pipeline register also. therefore, data for the first burst write cycle must be applied on the dq pins on the next clock cycle after the write command is issued. the remaining data inputs must be supplied on each subsequent rising clock edge until the burst length is completed. when the burst has finished, any additional data supplied to the dq pins will be ignored. spt03968 clk read a t0 t1 t2 t3 t4 t5 t6 command dout a0 dout a1 dout a2 dout a3 nop nop nop nop nop cas latency = 2 , dq's ck2 t registered dimm burst read operation (bl = 4) device nop dout a1 dout a0 dout a2 dout a3 cas latency = 3 dimm , dq's ck3 t one clock added for on-dimm pipeline register reg-dimm latency = 1
