CMOS SDRAM
- 3 -
Rev. 1.3 (Oct. 2001)
The K4S643232E 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.
3.3V power supply
LVTTL compatible with multiplexed address
Four banks operation
