E2L0013-17-Y1 ¡ Semiconductor ¡ Semiconductor MSM514262 262,144-Word ¥ 4-Bit Multiport DRAM This version: Jan. 1998 MSM514262 Previous version: Dec. 1996 DESCRIPTION The MSM514262 is an 1-Mbit CMOS multiport DRAM composed of a 262,144-word by 4-bit dynamic RAM and a 512-word by 4-bit SAM. Its RAM and SAM operate independently and asynchronously. The MSM514262 supports three types of operation : random access to RAM port, high speed serial access to SAM port and bidirectional transfer of data .

Semiconductor MSM514265E This version:Aug.2000 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.

E2L0013-17-Y1 ¡ Semiconductor ¡ Semiconductor MSM514262 262,144-Word ¥ 4-Bit Multiport DRAM This version: Jan. 1998 MSM514262 Previous version: Dec. 1996 DESCRIPTION The MSM514262 is an 1-Mbit CMOS multiport DRAM composed of a 262,144-word by 4-bit dynamic RAM and a 512-word by 4-bit SAM. Its RAM and SAM operate independently and asynchronously. The MSM514262 supports three types of operation : random access to RAM port, high speed serial access to SAM port and bidirectional transfer of data between any selected row in the RAM port and the SAM port. In addition to the conventional multiport DRAM operating modes, the MSM514262 features the block write and flash write functions on the RAM port and a split data transfer capability on the SAM port. The SAM port requires no refresh operation because it uses static CMOS flip-flops. FEATURES • Single power supply: 5 V ± 10% • Full TTL compatibility • Multiport organization RAM: 256K word ¥ 4 bits SAM: 512 word ¥ 4 bits • Fast page mode • Write per bit • Masked flash write • Masked block write • RAS only refresh • CAS before RAS refresh • Hidden refresh • Serial read/write • 512 tap location • Bidirectional data transfer • Split transfer • Masked write transfer • Refresh: 512 cycles/8 ms • Package options: 28-pin 400 mil plastic ZIP (ZIP28-P-400-1.27) 28-pin 400 mil plastic SOJ (SOJ28-P-400-1.27) (Product : MSM514262-xxZS) (Product : MSM514262-xxJS) xx indicates speed rank. PRODUCT FAMILY Family MSM514262-70 MSM514262-80 MSM514.
