2,097,152-Word ¥ 32-Bit DRAM MODULE : FAST PAGE MODE TYPE WITH EDO
DESCRIPTION
The Oki MSC2323258A-xxBS4/DS4 is a fully decoded 2,097,152-word ¥ 32-bit CMOS dynamic
random access memory composed of two 16-Mb (1M ¥ 16) DRAMs in SOJ. The mounting of two
DRAMs together with decoupling capacitors on a 72-pin glass epoxy SIMM Package supports
any application where high density and large capacity of storage memory are required.
FEATURES
• 2,097,152-word ¥ 32-bit organization
• 72-pin SIMM
• Single 5 V supply 10% tolerance
• Input
• Output : TTL compatible, 3-state, nonlatch
• Refresh : 1024 cycles/16 ms
• CAS before RAS refresh, CAS before RAS hidden refresh, RAS-only refresh capability
• Fast Page Mode with EDO capability
