Winbond Electronics Corporation W9464G6IH
W9464G6IH is a CMOS Double Data Rate synchronous dynamic random access memory (DDR SDRAM); organized as 1M words × 4 banks × 16 bits. The -4 is compliant to the DDR500/CL3 and CL4 specification. The -5/-5I is compliant to the DDR400/CL3 specification (the -5I grade which is guaranteed to support -40°C ~ 85°C).GENERAL DESCRIPTION
W9464G6IH delivers a data bandwidth of up to 500M words per second (-4). To fully comply with the personal computer industrial standard, W9464G6IH is sorted into the following speed grades: -4, -5, -5I, -6 and -6I. The -6/-6I is compliant to the DDR333/CL2.5 specification (the -6I grade which is guaranteed to support -40°C ~ 85°C). All Inputs reference to the positive edge of CLK (except for DQ, DM and CKE). The timing reference point for the differential clock is when the CLK and CLK signals cross during a transition. Write and Read data are synchronized with the both edges of DQS (Data Strobe). By having a programmable Mode Register, the system can change burst length, latency cycle, interleave or sequential burst to maximize its performance. W9464G6IH is ideal for any high performance applications. 2.FEATURES
