K4C89183AF
4,194,304-WORDS x 4 BANKS x 18-BITS DOUBLE DATA RATE Network-DRAM
DESCRIPTION
K4C89183AF is a CMOS Double Data Rate Network-DRAM containing 301,989,888 memory cells. K4C89183AF is organized as
4,194,304-words x 4 banks x18 bits. K4C89183AF feature a fully synchronous operation referenced to clock edge whereby all opera-
tions are synchronized at a clock input which enables high performance and simple user interface coexistence. K4C89183AF can oper-
ate fast core cycle compared with regular DDR SDRAM.
K4C89183AF is suitable for Server, Network and other applications where large memory density and low power consumption are
required. The Output Driver for Network-DRAM is capable of high quality fast data transfer under light loading condition.

Fully Synchronous Operation
- Double Data Rate (DDR)
- Data input/output are synchronized with both edges of DS / QS.
- Differential Clock (CLK and CLK) inputs
- CS, FN and all address input signals are sampled on the positive edge of CLK.
- Output data (DQs and QS) is aligned to the crossings of CLK and CLK.
Fast clock cycle time of 3.0 ns minimum
- Clock : 333 MHz maximum
- Data : 666 Mbps/pin maximum
Quad Independent Banks operation
Fast cycle and Short Latency
Uni-directional Data Strobe
Distributed Auto-Refresh cycle in 3.9us
Power Down Mode
Variable Write Length Control
Write Latency = CAS Latency-1
Programable CAS Latency and Burst Length
