MH16V7245BATJ -5, -6
HYPER PAGE MODE 1207959552 - BIT ( 16777216 - WORD BY 72 - BIT ) DYNAMIC RAM
DESCRIPTION
The MH16V7245BATJ is 16777216-word x 72-bit dynamic
ram module. This consist of eighteen industry standard 16M
x 4 dynamic RAMs in TSOP and three industry standard input
buffer in TSSOP.
The mounting of TSOP 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 a /RAS-Only refresh or /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 1TTL loads and 50pF,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+/-10uAI) and is not reference to VOH(min) or VOL(max).

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 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: Either tDZC or tDZO must be satisfied.
20: Either tRDD or tCDD or tODD must be satisfied.
21: tT is measured between VIH(min) and VIL(max).

Note 23: tRWC is specified as tRWC(min)=tRAC(max)+tODD(min)+tRWL(min)+tRP(min)+4tT.
24: tWCS, tCWD,tRWD ,tAWD and,tCPWD are specified as reference points only. If tWCS≥tWCS(min) the cycle is an early write cycle
and the DQ pins will remain high impedance throughout the entire cycle. If tCWD≥tCWD(min), tRWD≥tRWD (min), tAWD≥tAWD(min)
and tCPWD≥tCPWD(min) (for Hyper 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) of the DQ (at access time and until /CAS or /OE
goes back to VIH) is indeteminate.
