W9864G6JH-6

Product Summary

The W9864G6JH-6 is a high-speed synchronous dynamic random access memory (SDRAM), organized as 512K words × 2 banks × 16 bits. The W9864G6JH-6 delivers a data bandwidth of up to 200M words per second. For different application, W9864G6JH-6 is sorted into the following speed grades: -5/-6/-6I/-6A/-7 and -7I. The -5 parts can run up to 200MHz/CL3 or 143MHz/CL2. The -6/-6I/-6A parts can run up to 166MHz/CL3 (the -6I industrial grade, -6A automotive grade which is guaranteed to support -40℃ ~ 85℃). The -7/-7I parts can run up to 143MHz/CL3 (the -7I grade which is guaranteed to support -40℃ ~ 85℃). Accesses to the SDRAM are burst oriented. Consecutive memory location in one page can be accessed at a burst length of 1, 2, 4, 8 or full page when a bank and row is selected by an ACTIVE command. Column addresses are automatically generated by the SDRAM internal counter in burst operation. Random column read is also possible by providing its address at each clock cycle. The multiple bank nature enables interleaving among internal banks to hide the precharging time. By having a programmable Mode Register, the system can change burst length, latency cycle, interleave or sequential burst to maximize its performance. W9864G6JH-6 is ideal for main memory in high performance applications.
