GENERAL DESCRIPTION
W9825G6JH is a high-speed synchronous dynamic random access memory (SDRAM), organized as 4M words 4 banks 16 bits. W9825G6JH delivers a data bandwidth of up to 200M words per second (-5). To fully comply with the personal computer industrial standard, W9825G6JH is sorted into the following speed grades: -5, -6, -6I, -6A, -6L, -75 and 75L. The -6I/-6A/-6L grade parts are compliant to the 166MHz/CL3 specification (the -6I industrial grade, -6A automotive grade which is guaranteed to support -40°C ~ 85°C). The -75/75L is compliant to the 133MHz/CL3 specification. The -6L and 75L parts support self refresh current IDD6 max. 1.5 mA. 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.
