MSC23409C/CL-xxDS9
4,194,304-Word ¥ 9-Bit DRAM MODULE : FAST PAGE MODE TYPE
DESCRIPTION
The OKI MSC23409C/CL-xxDS9 is a fully decoded 4,194,304-word ¥ 9-bit CMOS Dynamic
Random Access Memory Module composed of nine 4-Mb DRAMs (4M ¥ 1) in SOJ packages
mounted with nine decoupling capacitors on a 30-pin glass epoxy single-inline package. This
module is generally used for memory expansion in parity applications such as workstations. The
low-power version (CL) offers reduced power consumption for mobile computing applications
like laptops and palmtops.
FEATURES
• 4-Meg ¥ 9-bit organization
• 30-Pin Socket Insertable Module
MSC23409C/CL-xxDS9 : Solder tab
• Single 5 V supply ±10% tolerance
• Access times : 60, 70, 80 ns
• Input : TTL compatible
• Output : TTL compatible, 3-state
• Refresh : 1024 cycles/16 ms (128 ms : L-version)
• CAS before RAS refresh, CAS before RAS hidden refresh, RAS-only refresh capability
• Multi-bit test mode capability
• Fast Page Mode capability
