DDR1 SO-DIMM 333MHz 1GB

The CIR-S1SUME3301G is 128M words X 64 bits,2 Ranks Double Data Rate (DDR) SDRAM Small outline dual in-line Memory module, mounted 16 pieces of 1GB bits DDR SDRAM(64Mx8) sealed in TSOPII package.  Read and write operations are performed at the cross points of the CK and the / CK. This high-speed data transfer is realized by the 2 bits prefetch-pipelined architecture. Data strobe (DQS) both for read and write are available for high speed and reliable data bus design. By setting extended mode register, the on-chip Delay locked loop (DDL) can be set enable or disable.
