KM432S2030B
CMOS SDRAM
REV. 4 July 1998
Preliminary
The KM432S2030B is 67,108,864 bits synchronous high data
rate Dynamic RAM organized as 4 x 524,288 words by 32 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
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 (4K cycle)
