262,144-Word ¥ 16-Bit DYNAMIC RAM : FAST PAGE MODE TYPE WITH EDO
DESCRIPTION
The MSM514265C/CSL is a 262,144-word ¥ 16-bit dynamic RAM fabricated in Oki's silicon-gate
CMOS technology. The MSM514265C/CSL achieves high integration, high-speed operation, and
low-power consumption because Oki manufactures the device in a quadruple-layer polysilicon/
single-layer metal CMOS process. The MSM514265C/CSL is available in a 40-pin plastic SOJ or 44/
40-pin plastic TSOP. The MSM514265CSL (the self-refresh version) is specially designed for lower-
power applications.
FEATURES
• 262,144-word ¥ 16-bit configuration
• Single 5 V power supply, 10% tolerance
• Input
• Output : TTL compatible, 3-state
• Refresh : 512 cycles/8 ms, 512 cycles/128 ms (SL version)
• Fast page mode with EDO, read modify write capability
• CAS before RAS refresh, hidden refresh, RAS-only refresh capability
• CAS before RAS self-refresh capability (SL version)
• Package options:
