Serial-parallel interface circuit with nonvolatile memory

摘要

A serial-parallel interface circuit with nonvolatile memories is provided. A control module generates a plurality of control signals, wherein the control signals include readout and write-in control signals and memory programming control signals. An input terminal receives a plurality of digital data from external. The digital data are transmitted to the input terminal serially. Memory modules are coupled to the input terminal and receive the control signals from the control module. The input terminal transmits the digital data to the memory modules. One of the memory modules includes a memory unit, and the memory unit stores or transmits one bit of the digital data based on a high voltage control signal and a memory control signal. A plurality of output signal lines are respectively coupled to the memory modules. The memory unit transmits the one bit of the digital data to one of the output signal lines.
