This vers ion: Mar. 3. 1999
DESCRIPTION
The MSC23232D/DL-xxBS16/DS16 is a fully decoded, 2,097,152-word x 32-bit CMOS dynamic random access
m emory modul e composed of six teen 4Mb DRAMs in SOJ packages mounted with sixt een decoupli ng capacit ors
on a 72-pi n glass epox y si ngle- inl i ne package. Thi s modul e supports any appl ic ati on where hi gh densit y and lar ge
capacity of storage memory are required. The MSC23232DL (the low-power version) is specially designed for
lower-power applicat ions.

Notes: 1. A start- up delay of 200µs is required after power-up, fol lowed by a m ini mum of eight initializat ion cycles
(/RA S only refr esh or / CA S befor e /RAS refr esh) before pr oper device operat ion i s achieved.
2. The AC c har ac teri stics assum es tT = 5ns.
3. VIH(Min. ) and VIL(Max .) are ref erence lev el s for measuri ng input t im ing signal s. Transit ion ti me ( tT) are
m easured bet ween VIH and VIL.
4. This parameter i s measured with a load c ircuit equivalent to 2TT L loads and 100pF.
5. Operation within the tRCD(M ax. ) li mit ensures that t RAC(Max . ) can be met.
tRCD(Max.) is s pecified as a reference point only . If tRCD is greater than the s pecified tRCD(Max.) limit, then
the acc ess ti me is controlled by tCAC.
6. Operation within the tRAD(Max.) li mit ensures that tRAC(Max. ) can be met.
tRAD(Max.) is s pecified as a reference point only. If tRAD is greater than the specified tRAD(Max.) limit, then
the acc ess ti me is controlled by tAA.
7. tOFF(Max.) define the time at w hich the output achieves the open circuit condition and are not referenced
to out put voltage levels.
8. tRCH or tRRH must be satisfied for a read cycle.
9. The test mode is initiated by performing a /WE and /CAS before /RAS refresh cycle. This mode is
latched and remains in effect until the exit cycle is generated. The test mode specified in this data sheet
is a 2-bit parall el test function. CA0 is not used. In a read cycle, if al l internal bits are equal , t he DQ pin
will indicate a high lev el. If any internal bits are not equal, the DQ pin will indicate a low lev el.
The test m ode i s cleared and t he mem ory dev i ce r eturned t o i ts norm al operating stat e by a / RAS onl y
refresh or /CAS before /RAS ref resh cycle.
10. In a test mode read cycle, the value of access time parameters is delayed for 5ns for the specified value.
These parameters should be specified in test mode cycle by adding the abov e value to the specified
value in this data sheet.
