SDRAM

1. GENERAL DESCRIPTION

54S416T is a high-speed synchronous dynamic random access memory (SDRAM), organized as

1M words x 4 banks x 16 bits. Using pipelined architecture.

54S416T delivers a data bandwidth of up to 400M bytes per second (-5). For different application,

54S416T is sorted into the following speed grades: -5, -6, -7. The -5 parts can run up to 200

MHz/CL3. The -6 parts can run up to 166 MHz/CL3. The -7 parts can run up to 143 MHz/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. 50S416T is ideal for main memory in

high performance applications.
