128MB- 16Mx64 DDR SDRAM UNBUFFERED W/PLL
FEATURES
Double-data-rate architecture Speed of 100MHz, 133MHz and 166MHz Bi-directional data strobes (DQS) Differential clock inputs (CK & CK#) Programmable Read Latency 2,2,5 (clock) Programmable Burst Length (2,4,8) Programmable Burst type (sequential & interleave) Edge aligned data output, center aligned data input Auto and self refresh Serial presence detect JEDEC standard 200 pin SO-DIMM package Power Supply: 2.5V 0.25V Synchronous design allows precise cycle control with the use of system clock. Data I/O transactions are possible on both edges and Burst Lenths allow the same device to be useful for a variety of high bandwidth, high performance memory system applications.
DESCRIPTION
The WED3DG6418S is a 16Mx64 Double Data Rate SDRAM memory module based on 128Mb DDR SDRAM component. The module consists of eight 16Mx8 DDR SDRAMs in 66 pin TSOP package mounted on a 200 Pin FR4 substrate.
