MSM511664C/CL
65,536-Word ¥ 16-Bit DYNAMIC RAM : FAST PAGE MODE TYPE (BYTE WRITE)
DESCRIPTION
The MSM511664C/CL is a 65,536-word ¥ 16-bit dynamic RAM fabricated in Oki's silicon-gate CMOS
technology. The MSM511664C/CL 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 MSM511664C/CL is available in a 40-pin plastic SOJ or 44/40-pin plastic
TSOP. The MSM511664CL (the low-power version) is specially designed for lower-power applications.
FEATURES
• 65,536-word ¥ 16-bit configuration
• Single 5 V power supply, ±10% tolerance
• Input : TTL compatible, low input capacitance
• Output : TTL compatible, 3-state
• Refresh : 256 cycles/4 ms, 256 cycles/32 ms (L-version)
• Byte write and fast page mode, read modify write capability
• CAS before RAS refresh, hidden refresh, RAS-only refresh capability
• Package options:
