Product Summary

The W9464G6IH-5 is a CMOS Double Data Rate synchronous dynamic random access memory (DDR SDRAM); organized as 1M words × 4 banks × 16 bits. The W9464G6IH-5 delivers a data bandwidth of up to 500M words per second (-4). To fully comply with the personal computer industrial standard, the W9464G6IH-5 is sorted into the following speed grades: -4, -5, -5I, -6 and -6I. The -4 is compliant to the DDR500/CL3 and CL4 specification. 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.
