Rev. 0.0 Aug. 1999 K4S281632B 2M x 16Bit x 4 Banks Synchronous DRAM FEATURES JEDEC standard 3.3V power supply LVTTL compatible with multiplexed address Four 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 64ms refresh period (4K cycle) CMOS SDRAM GENERAL DESCRIPTION The K4S281632B is 134,217,728 bits synchronous high data rate Dynamic RAM organized as 4 x 2,097,152 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.
