KM44S64230A
CMOS SDRAM
REV. 0 May '98
Preliminary
The KM44S64230A is 268,435,456 bits synchronous high data
rate Dynamic RAM organized as 4 x 16,785,216 words by 4
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, programma-
ble burst length and programmable latencies allow the same
device to be useful for a variety of high bandwidth, high perfor-
mance 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)
