Programmable Logic Device With On-Chip User Non-Volatile Memory

摘要

The present invention discloses a programmable logic device with on-chip user non-volatile memory, comprising: a programmable logic array, which is a user programmable logic array and comprises a SRAM array and a logic block array with an interface; the SRAM array is used to store configuration data to control the logic block array in real time, therefore, the logic block can be formed to perform the function a user desires; a non-volatile memory block, comprising one or more segments storing configuration data and one or more segments storing user data which is used during FPGA's normal operation after configuration; the non-volatile memory block has only one interface, and the non-volatile memory block connects to a programming controller through the interface; a programming controller, which can randomly access the non-volatile memory through a data bus, an address bus, and corresponding control signals.
