GENERAL DESCRIPTION
W9425G6EH is a CMOS Double Data Rate synchronous dynamic random access memory (DDR SDRAM), organized as 4,194,304 words × 4 banks × 16 bits. W9425G6EH delivers a data bandwidth of up to 500M words per second (-4). To fully comply with the personal computer industrial standard, W9425G6EH is sorted into the following speed grades: -4, -5, -5I, -6 and -6I. 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). The -6/-6I is compliant to the DDR333/CL2.5 specification (the -6I grade which is guaranteed to support -40°C ~ 85°C).
