GENERAL DESCRIPTION
W986432AH is a high-speed synchronous dynamic random access memory (SDRAM), organized as
512K words
W986432AH delivers a data bandwidth of up to 732M bytes per second (-55). For different
application, W986432AH is sorted into four speed grades: -55, -6, -7 and -8.
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. W986432AH is ideal for main memory in
high performance applications.
