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.
