W986416DH

1. GENERAL DESCRIPTION

W986416DH is a high-speed synchronous dynamic random access memory (SDRAM), organized as

1M words x 4 banks x 16 bits. Using pipelined architecture and 0.175 µm process technology,

W986416DH delivers a data bandwidth of up to 400M bytes per second (-5). For different application,

W986416DH 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, we also provide a low power option, the grade of -7L, with Self Refresh

Current under 400 µA and work well at 2.7V during Self Refresh Mode. For special application, we

provide extended temperature option the grade of -6I can work well in wide temperature from -40° C to

85° C.

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. W986416DH is ideal for main memory in

high performance applications.
