KM44S4020C
REV. 5 Feb. '98
CMOS SDRAM
The KM44S4020C is 16,777,216 bits synchronous high data
rate Dynamic RAM organized as 2 x 2,097,152 words by 4 bits,
fabricated with SAMSUNG
′
s high performance CMOS technol-
ogy. 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 mem-
ory system applications.
JEDEC standard 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
64ms refresh period (4K Cycle)
