W9864G2JH
1. GENERAL DESCRIPTION
W9864G2JH is a high-speed synchronous dynamic random access memory (SDRAM), organized as
512K words  4 banks  32 bits. W9864G2JH delivers a data bandwidth of up to 200M words per
second. For different application, W9864G2JH is sorted into the following speed grades: -5, -6, -6I, -6A,
-6K and -7. The -5 parts can run up to 200MHz/CL3. The -6, -6I, -6A and -6K parts can run up to 166
MHz/CL3, -6I industrial grade, -6A automotive grade which is guaranteed to support -40°C ≤ TA ≤ 85°C.
If -6K automotive grade offered, has two simultaneous requirements: ambient temperature (TA)
surrounding the device cannot be less than -40°C or greater than +105°C, and the case temperature
(TCASE) cannot be less than -40°C or greater than +105°C.) The -7 parts can run up to 143 MHz/CL3.
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. W9864G2JH is ideal for main memory in
high performance applications.
