131,072-Word ¥ 8-Bit DYNAMIC RAM : FAST PAGE MODE TYPE
DESCRIPTION
The MSM518128/L is a 131,072-word ¥ 8-bit dynamic RAM fabricated in Oki's silicon-gate CMOS
technology. The MSM518128/L 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 MSM518128/L is available in a 26/24-pin plastic SOJ. The MSM518128L
(the low-power version) is specially designed for lower-power applications.
FEATURES
• 131,072-word ¥ 8-bit configuration
• Single 5 V power supply, ±5% tolerance
• Input : TTL compatible, low input capacitance
• Output : TTL compatible, 3-state
• Refresh : 512 cycles/8 ms, 512 cycles/64 ms (L-version)
• Fast page mode, read modify write capability
• CAS before RAS refresh, hidden refresh, RAS-only refresh capability
• Package:
26/24-pin 300 mil plastic SOJ (SOJ26/24-P-300-1.27) (Product : MSM518128/L-xxJS)
xx indicates speed rank.
