W986416AH

W986416AH is a high speed synchronous dynamic random access memory (SDRAM) , organized as 1M words x 4 banks x 16 bits. Using pipelined architecture, W986416AH delivers a data bandwidth of up to 250M bytes per second (-8H). To fully comply to the PC100/66 personal computer industrial standard, W986408AH is sorted into three speed grades: -8H, -8N/8L, and -10. The -8H is compliant to the PC100/CL2 specification, the -8N is compliant to PC100/CL3 specification, and -10 is compliant to PC/66 specification.

Accesses to the SDRAM W986416AH 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 W986416AH internal counrter 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 legnth, latency cycle, interleave or sequential burst to maximize its performance. W986416AH is ideal for main memory in high performance applications.
