E2G0023-17-41 ¡ Semiconductor MSM514400D/DL ¡ Semiconductor This version: Jan. 1998 MSM514400D/DL Previous version: May 1997 1,048,576-Word ¥ 4-Bit DYNAMIC RAM : FAST PAGE MODE TYPE DESCRIPTION The MSM514400D/DL is a 1,048,576-word ¥ 4-bit dynamic RAM fabricated in Oki's silicon-gate CMOS technology. The MSM514400D/DL 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 MSM514400D/DL is available in a 26/20-pin plastic SOJ, 20pin plastic ZIP, or 26/20-pin plastic TSOP. The MSM514400DL (the low-power version) is specially designed for lower-power applications. FEATURES 1,048,576-word ¥ 4-bit configuration Single 5 V power supply, ± 10% tolerance Input : TTL compatible, low input capacitance Output : TTL compatible, 3-state Refresh : 1024 cycles/16 ms, 1024 cycles/128 ms (L-version) Fast page mode, read modify write capability CAS before RAS refresh, hidden refresh, RAS-only refresh capability Multi-bit test mode capability Package options: 26/20-pin 300 mil plastic SOJ (SOJ26/20-P-300-1.27) (Product : MSM514400D/DL-xxSJ) 20-pin 400 mil plastic ZIP (ZIP20-P-400-1.27) (Product : MSM514400D/DL-xxZS) 26/20-pin 300 mil plastic TSOP (TSOPII26/20-P-300-1.27-K) (Product : MSM514400D/DL-xxTS-K) xx indicates speed rank.
