W9812G6JH Datasheet



W9812G6JH is a high-speed synchronous dynamic random access memory (SDRAM), organized as2M words× 4 banks × 16 bits. W9812G6JH delivers a data bandwidth of up to 200M words persecond. For different application, W9812G6JH is sorted into the following speed grades: -5/-6/-6I/-6Aand -75. The -5 is compliant to the 200MHz/CL3 specification. The -6/-6I/-6A is compliant to the166MHz/CL3 specification (the -6I industrial grade, -6A automotive grade which is guaranteed tosupport -40°C ~ 85°C). The -75 is compliant to the 133MHz/CL3 specification.Accesses to the SDRAM are burst oriented. Consecutive memory location in one page can beaccessed at a burst length of 1, 2, 4, 8 or full page when a bank and row is selected by an ACTIVEcommand. Column addresses are automatically generated by the SDRAM internal counter in burstoperation. Random column read is also possible by providing its address at each clock cycle. Themultiple 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. W9812G6JH is ideal for main memory inhigh performance applications.
