Rev 1.1 Jan '03 K4S161622E 512K x 16Bit x 2 Banks Synchronous DRAM FEATURES 3.3V power supply LVTTL compatible with multiplexed address Dual banks operation MRS cycle with address key programs -. CAS Latency ( 2 & 3) -. Burst Length (1, 2, 4, 8 & full page) -. Burst Type (Sequential & Interleave) All inputs are sampled at the positive going edge of the system clock Burst Read Single-bit Write operation DQM for masking Auto & self refresh 15.6us refresh duty cycle (2K/32ms) CMOS SDRAM GENERAL DESCRIPTION The K4S161622E is 16,777,216 bits synchronous high data rate Dynamic RAM organized as 2 x 524,288 words by 16 bits, fabricated with SAMSUNG′s high performance CMOS technology. Synchronous design allows precise cycle control with the use of system clock I/O transactions are possible on every clock cycle. Range of operating frequencies, programmable burst length and programmable latencies allow the same device to be useful for a variety of high bandwidth, high performance memory system applications.
