K4S280832M
CMOS SDRAM
Rev. 0.0 Aug. 1999
The K4S280832M is 134,217,728 bits synchronous high data
rate Dynamic RAM organized as 4 x 4,194,304 words by 8 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
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)
