MSC23B236A-xxBS8/DS8
MSC23B236A-xxBS8/DS8
2,097,152-Word ¥ 36-Bit DRAM MODULE : FAST PAGE MODE TYPE
DESCRIPTION
The Oki MSC23B236A-xxBS8/DS8 is a fully decoded 2,097,152-word ¥ 36-bit CMOS dynamic
random access memory composed of four 16-Mb (1M ¥ 16) DRAMs in SOJ and four 2-Mb (1M
¥ 2) DRAMs in SOJ. The mounting of eight 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 ¥ 36-bit (Parity) organization
• 72-pin SIMM
MSC23B236A-xxBS8 : Gold tab
MSC23B236A-xxDS8 : Solder tab
• Single 5 V supply ±10% tolerance
• Input : TTL compatible
• 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 capability
