PIN CONFIGURATION (TOP VIEW)
DESCRIPTION
The MH2M365CXJ/CNXJ is 2097152-word x 36-bits dynamic RAM. This consists of four industry standard 1M x 16 dynamic RAMs in SOJ and two industry 1M x 4 dyanmic RAMs in SOJ. The mounting of SOJ on a single in-line package provides any application where high densities and large quantities of memory are required. This is a socket-type memory module,suitable for easy interchange or addition of modules.

Note 2: Current flowing into an IC is positive, out is negative. 3: Icc1 (AV), Icc3 (AV) and Icc4 (AV) are dependent on cycle rate. Maximum current is measured at the fastest cycle rate. 4: Icc1 (AV) and Icc4 (AV) are dependent on output loading. Specified values are obtained with the output open. 5: Column Address can be changed once or less while RAS=VIL and CAS=VIH .

Note 6: An initial pause of 500µs is required after power-up followed by a minimum of eight initialization cycles (any combination of cycles containing a RAS clock such as RAS-Only 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 16.4 ms) of RAS inactivity before proper device operation is achieved. 7: Measured with a load circuit equivalent to VOH=2.4V(IOH=-5mA) / VOL=0.4V(IOL=-4.2mA) load 100pF. The reference levels for measuring of output signal are 2.0V(VOH) and 0.8V(VOL). 8: Assumes that tRCD tRCD(max) and tASC tASC(max) and tCP t CP(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: tWEZ(max) ,tOFF(max) and tREZ(max)defines the time at which the output achieves the high impedance state ( IOUT ≤ I ± 10 µA 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 =3ns. 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 tRAD ≤ tRAD(max) and tASC ≤ tASC(max), access time is controlled exclusively by tAA. 18: tASC(max) is specified as a reference point only. If tRCD ≥ tRCD(max) and tASC ≥ tASC(max), access time is controlled exclusively by tCAC. 19: tDZC must be satisfied. 20: Either tRDD or tCDD or tODD must be satisfied. 21: tT is measured between VIH(min) and VIL(max).
