Product Summary
The W971GG6JB-25 is a 1G bits DDR2 SDRAM, organized as 8,388,608 words × 8 banks × 16 bits. This device achieves high speed transfer rates up to 1066Mb/sec/pin (DDR2-1066) for various applications. The W971GG6JB-25 is sorted into the following grade parts: -18, -25, 25L, 25I, 25A, 25K and -3. The -18 grade parts is compliant to the DDR2-1066 (6-6-6) specification. The -25/25L/25I/25A/25K grade parts are compliant to the DDR2-800 (5-5-5) specification. All I/Os of the W971GG6JB-25 are synchronized with a single ended DQS or differential DQS- DQS pair in a source synchronous fashion.
