HYPER PAGE MODE 603979776 - BIT ( 8388608 - WORD BY 72 - BIT ) DYNAMIC RAM
DESCRIPTION
The MH8V7245BAZTJ is 8388608-word x 72-bit dynamic
ram module. This consist of nine industry standard 8M x 8
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 /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.
Output disable time after /CAS 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 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 indeterminate.
