W9825G6KH
1. GENERAL DESCRIPTION
W9825G6KH is a high-speed synchronous dynamic random access memory (SDRAM), organized as
4M words 4 banks 16 bits. W9825G6KH delivers a data bandwidth of up to 200M words per
second. To fully comply with the personal computer industrial standard, W9825G6KH is sorted into the
following speed grades: -5, -5I, -6, -6I, -6L, -75 and 75L. The -5/-5I grade parts are compliant to the
200MHz/CL3 specification (the -5I industrial grade which is guaranteed to support -40°C ≤ TA ≤ 85°C).
The -6/-6I/-6L grade parts are compliant to the 166MHz/CL3 specification (the -6I industrial grade
which is guaranteed to support -40°C ≤ TA ≤ 85°C). The -75/75L is compliant to the 133MHz/CL3
specification. The -6L and 75L parts support self refresh current IDD6 max. 1.5 mA.
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. W9825G6KH is ideal for main memory in
high performance applications.
