Product Summary

The W9425G6JH-5 is a CMOS Double Data Rate synchronous dynamic random access memory (DDR SDRAM), organized as 4,194,304 words×4 banks×16 bits. W9425G6JH delivers a data bandwidth of up to 500M words per second (-4). To fully comply with the personal computer industrial standard, W9425G6JH-5 is sorted into the following speed grades: -4, -5 and -5I. 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).
