W9812G6GH

1. GENERAL DESCRIPTION

W9812G6GH is a high-speed synchronous dynamic random access memory (SDRAM), organized as

2M words × 4 banks × 16 bits. Using pipelined architecture and 0.11 µm process technology,

W9812G6GH delivers a data bandwidth of up to 166M words per second (-6). For different application,

W9812G6GH is sorted into two speed grades: -6/6C/6I, -75. The –6/6C/6I is compliant to the

166Mhz/CL3 specification, the -75 is compliant to the 133MHz/CL3 specification.

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. W9812G6GH is ideal for main memory in

high performance applications.
