Product Summary

The W948D2FBJX6E is a high-speed mobile double data rate synchronous dynamic random access memory (LPDDR SDRAM), Using pipelined architecture, An access to the LPDDR SDRAM is burst oriented. Consecutive memory location in one page can be accessed at a burst length of 2, 4, 8 and 16 when a bank and row is selected by an ACTIVE command. Column addresses are automatically generated by the LPDDR SDRAM internal counter in burst operation. Random column read of the W948D2FBJX6E is also possible by providing its address at each clock cycle.
