W9816G6CH

1. GENERAL DESCRIPTION

W9816G6CH is a high-speed synchronous dynamic random access memory (SDRAM), organized as

512K words × 2 banks × 16 bits. Using pipelined architecture and 0.13 µm process technology,

W9816G6CH delivers a data bandwidth of up to 400M bytes per second (-5). For different applications

the W9816G6CH is sorted into the following speed grades: -5, -6, -7. The -5 parts can run up to

200Mhz/CL3. The -6 parts can run up to 166Mhz/CL3. The -7 parts can run up to 143Mhz/CL3. For

handheld device application.

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. W9816G6CH is ideal for main memory in

high performance applications.
