MB85R4001A概要说明书

MB85R4001A is a 4M-bits FRAM LSI using the ferroelectric process and CMOS process
technologies for forming the nonvolatile memory cells.
Because FRAM is able to write high-speed even though a nonvolatile memory,
it is suitable for the log management and the storage of the resume data, etc.
MB85R4001A uses a pseudo-SRAM interface compatible with conventional asynchronous SRAM.
