DESCRIPTION
The MH8V7245BWZTJ is 8388608-word x 72-bit dynamic ram module. This consist of nine industry standard 8M x 8 dynamic RAMs in TSOP and one industry standard EEPROM in TSSOP. The mounting of TSOPs and TSSOP on a card edge dual in-line package provides any application where high densities and large of quantities memory are required. This is a socket-type memory module ,suitable for easy interchange or addition of module.

Note 6: An initial pause of 500us is required after power-up followed by a minimum of eight initialization cycles (any combination of cycles containing /CAS before /RAS refresh). Note the /RAS may be cycled during the initial pause . And any 8 /RAS or /RAS /CAS cycles are required after prolonged periods (greater than 64 ms) of /RAS inactivity before proper device operation is achieved. 7: Measured with a load circuit equivalent to 1 TTL load and 100pF,VOH=2.4V(IOH=-2mA) and VOL=0.4V(IOL=-2mA). The reference levels for measuring of output signals are 2.0V(VOH)and 0.8V(VOL). 8: Assumes that tRCD tRCD(max), tASC tASC(max) and tCP tCP(max). 9: Assumes that tRCD tRCD(max) and tRAD tRAD(max). If tRCD or tRAD is greater than the maximum recommended value shown in this table, tRAC will increase by amount that tRCD exceeds the value shown. 10: Assumes that tRAD tRAD(max) and tASC tASC(max). 11: Assumes that tCP tCP(max) and tASC tASC(max). 12: tOEZ (max), tWEZ(max), tOFF(max) and tREZ(max) defines the time at which the output achieves the high impedance state (IOUT I 10uA I ) and is not reference to VOH(min) or VOL(max). 13: Output is disabled after both /RAS and /CAS go to high.

Note 14: The timing requirements are assumed tT =2ns. 15: VIH(min) and VIL(max) are reference levels for measuring timing of input signals. 16: tRCD(max) is specified as a reference point only. If tRCD is less than tRCD(max), access time is tRAC. If tRCD is greater than tRCD(max), access time is controlled exclusively by tCAC or tAA. . 17: tRAD(max) is specified as a reference point only. If tRADtRAD(max) and tASCtASC(max), access time is controlled exclusively by tAA. 18: tASC(max) is specified as a reference point only.
