MH4V64AWXJ -5, -6
FAST PAGE MODE 268435456 - BIT ( 4194304 - WORD BY 64 - BIT ) DYNAMIC RAM
DESCRIPTION
PIN CONFIGURATION
The MH4V64AWXJ is 4194304-word x 64-bit dynamic
ram module. This consist of four industry standard 4M x
16 dynamic RAMs in SOJ and one industry EEPROM in
TSSOP.
85pin
1pin
The mounting of SOJs 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.

read, write, and read-modify-write operations,
a number of other functions, e.g., Fast page mode, /CAS
before /RAS refresh, and delayed-write. The input
conditions for each are shown in Table 1.

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 eight initialization 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 VOH=2.4V(IOH=-2mA) / VOL=0.4V(IOL=2mA) loads and 100pF.The reference levels for measuring of output
signals are 2.0V(VOH)and 0.8V(VOL).
8: Assumes that tRCD ³ tRCD(max), tASC ³ tASC(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 ³ tRAD(max) and tASC £ tASC(max).
11: Assumes that tCP £ tCP(max) and tASC ³ tASC(max).
12: tOFF (max) and tOEZ(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).

Note 13: The timing requirements are assumed tT =5ns.
14: VIH(min) and VIL(max) are reference levels for measuring timing of input signals.VIH(min) and VIL(max) of the switching characteristics are
2.0V and 0.8V respectively
15: 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.tRCD(min) is specified as tRCD(min) = tRAH(min) + 2tT + tASC(min) .
16: tRAD(max) is specified as a reference point only. If tRAD³ tRAD(max) and tASC£tASC(max), access time is controlled exclusively by tAA.
17: tASC(max) is specified as a reference point only. If tRCD³ tRCD(max) and tASC³ tASC(max), access time is controlled exclusively by tCAC.
18: Either tDZC or tDZO must be satisfied.
19: Either tCDD or tODD must be satisfied.
20: tT is measured between VIH(min) and VIL(max).

Note 22: tRWC is specified as tRWC(min)=tRAC(max)+tODD(min)+tRWL(min)+tRP(min)+5tT.
23:tWCS, tCWD,tRWD ,tAWD and,tCPWD are specified as reference points only. If tWCS³ tWCS(min) the cycle is an early write cycle and the DQ pins will remain
high impedance throughout the entire cycle. If tCWD³ tCWD(min), tRWD³ tRWD (min), tAWD³ tAWD(min) and tCPWD ³ tCPWD(min) (for Fast page mode cycle only),
the cycle is a read-modify-write cycle and the DQ will contain the data read from the selected address. If neither of the above condition (delayed write) is
satisfied,the DQ (at access time and until /CAS or /OE goes back to VIH) is indeterminate.
