Abstract

A programmable logic device unit, a non-volatile memory unit which stores data for programming the programmable logic device unit in a part of data storage area thereof and a control circuit which controls the non-volatile memory unit to allow the data stored in a part of the data storage area to be read at power-on time and supplied to the programmable logic device unit are integrally provided on a semiconductor chip. Based on the program data, the programmable logic device unit forms an interface for allowing the non-volatile memory unit to operate as at least one of a register, a flash memory, a random access memory, and a read-only memory.

Description

technical field [0001] The invention relates to a semiconductor integrated circuit device with a built-in non-volatile memory unit (unit) and a programmable logic device unit. Background technique [0002] Currently, commercial activities for manufacturing a semiconductor chip in which a system LSI unit is mounted around a nonvolatile memory unit composed of a NAND flash memory or the like are widespread. However, the specifications of the system LSI unit vary depending on the customer or the like, and the interface or the like must be changed according to the specifications. For this reason, there is a problem that a template must be prepared for each product at the time of manufacture, resulting in high development costs and lack of versatility. [0003] In addition, Japanese Patent Document 1 discloses a static latch that integrates a flash memory unit with an FPGA unit, a CPU, a RAM, etc. on a semiconductor chip and stores data for programming the FPGA unit in an SRAM, ...
