1. GENERAL DESCRIPTION
W982516BH is a high-speed synchronous dynamic random access memory (SDRAM), organized as
4M words
×
4 banks
×
16 bits. Using pipelined architecture and 0.175
μ
m process technology,
W982516BH delivers a data bandwidth of up to 143M words per second (-7). To fully comply with the
personal computer industrial standard, W982516BH is sorted into two speed grades: -7 and -75. The -
7 is compliant to the 143 MHz/CL3 or PC133/CL2 specification, the -75 is compliant to the PC133/CL3
specification, for handheld device application, we also provide a low power option, the 75L grade, with
Self Refresh Current under 1mA., and an industrial temperature option, the grade of 75I, which is
guranteed to support -40
°
C – 85
°
C.
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. W982516BH is ideal for main memory in
high performance applications.
