2 / 8 page  K6R1004C1B-C CMOS SRAM PRELIMINARY Rev 2.0 - 2 - February 1998 PRELIMINARY Preliminary 256K x 4 Bit (with OE)High-Speed CMOS Static RAM GENERAL DESCRIPTION FEATURES • Fast Access Time 8,10,12ns(Max.) • Low Power Dissipation Standby (TTL) : 50mA(Max.) (CMOS) : 10mA(Max.) Operating K6R1004C1B-8 : 150mA(Max.) K6R1004C1B-10 : 145mA(Max.) K6R1004C1B-12 : 140mA(Max.) • Single 5.0V ±10% Power Supply • TTL Compatible Inputs and Outputs • I/O Compatible with 3.3V Device • Fully Static Operation - No Clock or Refresh required • Three State Outputs • Center Power/Ground Pin Configuration • Standard Pin Configuration K6R1004C1B-J : 32-SOJ-400 The K6R1004C1B is a 1,048,576-bit high-speed Static Random Access Memory organized as 262,144 words by 4 bits. The K6R1004C1B uses 4 common input and output lines and has an output enable pin which operates faster than address access time at read cycle. The device is fabricated using SAM- SUNG ′s advanced CMOS process and designed for high- speed circuit technology. It is particularly well suited for use in high-density high-speed system applications. The K6R1004C1B is packaged in a 400 mil 32-pin plastic SOJ.
