The K4S560832D is 268,435,456 bits synchronous high data rate
Dynamic RAM organized as 4 x 8,392,608 words by 8bits, 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.
• 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 (8K Cycle)
