Hercules Microelectronics Assigned Patent

Hercules Microelectronics Co. Ltd., Beijing, China, has been assigned a patent (11,323,121) developed by Liu, Chengli, Wang, Haili, Chen, Zixian, and Ma, Ming, Beijing, China, for a “programmable device structure based on mixed function storage unit.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A programmable device structure based on a mixed function storage unit includes a storage unit SRAM and a mixed function unit, wherein the storage unit comprises n register units and at least one selection control bit, wherein n=2{circumflex over( )}x, and x is natural number, the register units are selected according to the selection control bit, and when the selection control bit selects the mixed function unit to serve as a lookup table, a logic function is achieved, or when the selection control bit selects the mixed function unit to serve as a multiplexer, a routing function is achieved. By multiplexing the register units, the programmable device structure achieves a routing function of a traditional FPGA and also provides a logic function, and the waste of resources is greatly reduced.”

The patent application was filed on January 8, 2018 (16/769,152).
