W971632AF

W971632AF is a 16,777216-bit synchronous graphic memory organized as 262,144 words x 2 banks x 32 bits. Using synchronous pipelined architecture, W971632AF delivers a data transmission rate of up to 143M words per second.

Accesses to the SGRAM W971632AF 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 SGRAM W971632AF 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. Using a pogrammable Mode Register, the system can change burst length, latency cycle, interleave or sequential burst to maximize its performance.

With write-per-bit and block-write functions, W971632AF is optimized for graphics drawing operation.
