MH4M36CJD-5,-6,-7
FAST PAGE MODE ( 4194304-WORD BY 36-BIT ) DYNAMIC RAM
DESCRIPTION
The MH4M36CJD is an 4M word by 36-bit dynamic
RAM module and consists of 8 industry standard
4M X 4 dynamic RAMs in TSOP and 4 industry
standard 4M X 1 dynamic RAMs in TSOP.
The ICs are mounted on both sides of small
ceracom PC boards and form a convenient 64-pin
WDIP package.

Note 5: 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 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 32 ms) of RAS inactivity before proper device operation is achieved.
6: Measured with a load circuit equivalent to 2TTL loads and 100pF.
7: Assumes that tRCD
≥
tRCD(max) and tASC
≥
tASC(max).
8: 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.
9: Assumes that tRAD
≥
tRAD(max) and tASC
≤
tASC(max).
10: Assumes that tCP
≤
tCP(max) and tASC
≥
tASC(max).
11: tOFF(max) and tOEZ (max) defines the time at which the output achieves the high impedance state ( | IOUT |
≤
10 uA) and is not reference to
VOH(min) or VOL(max).

Note 12: The timing requirements are assumed tT =5ns.
13: VIH(min) and VIL(max) are reference levels for measuring timing of input signals.
14: 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) +2tH+tASC(min).
15: tRAD(max) is specified as a reference point only. If tRAD
≥
tRAD(max) and tASC

16: tASC(max) is specified as a reference point only. If tRCD

17: Either tDZC or tDZO must be satisfied.
18: Either tCDD or tODD must be satisfied.
