Product Summary
The W986432DH-6 is a high-speed synchronous dynamic random access memory (SDRAM), organized as 512K words × 4 banks × 32 bits. Using pipelined architecture and 0.175 mm process technology, the W986432DH-6 delivers a data bandwidth of up to 800M bytes per second (5). For different application, the W986432-DH7 is sorted into four speed grades: -5, -55, -6, -7,-8. Accesses to the SDRAM is 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.
