MSM514265E
262,144-Word x 16-Bit DYNAMIC RAM : FAST PAGE MODE TYPE WITH EDO
DESCRIPTION
The MSM514265E is a 262,144-word × 16-bit dynamic RAM fabricated in Oki’s silicon-gate CMOS technology.
The MSM514265E achieves high integration, high-speed operation, and low-power consumption because Oki
manufactures the device in a quadruple-layer polysilicon/double-layer metal CMOS process. The MSM514265E
is available in a 40-pin plastic SOJ or 44/40-pin plastic TSOP.
FEATURES
• 262,144-word × 16-bit configuration
• Single 5V power supply, ±10% tolerance
• Input
: TTL compatible, low input capacitance
• Output : TTL compatible, 3-state
• Refresh : 512 cycles/8ms
• Fast page mode with EDO, read modify write capability
• CAS before RAS refresh, hidden refresh, RAS-only refresh capability
• Package options:
40-pin 400mil plastic SOJ
(SOJ40-P-400-1.27)
(Product : MSM514265E-xxJS)
44/40-pin 400mil plastic TSOP (TSOPII44/40-P-400-0.80-K) (Product : MSM514265E-xxTS-K)
xx indicates speed rank.
