GENERAL DESCRIPTION

W9864G6JH is a high-speed synchronous dynamic random access memory (SDRAM), organized as 1M words x 4 banks x 16 bits. W9864G6JH delivers a data bandwidth of up to 200M words per second. For different application, W9864G6JH is sorted into the following speed grades: -5/-6/-6I/-6A/-7/-7S. The -5 parts can run up to 200MHz/CL3. The -6/-6I/-6A parts can run up to 166MHz/CL3 (the -6I industrial grade, -6A automotive grade which is guaranteed to support -40°C ~ 85°C). The -7/-7S parts can run up to 143MHz/CL3 and with tRP= 18nS.
