Patent ID: 11947828
Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 15:
16. A system, comprising:
a memory device; and
a neural network processor configured to access the memory device;
wherein the memory device comprises:
a plurality of memory cells configured to store a plurality of binary numbers corresponding to data transmitted from/to the neural network processor;
a selection circuit configured to determine that a first address of a plurality of addresses received from a test circuit matches one of addresses of first memory cells in the plurality of memory cells to output the first address as a fault address, wherein the first memory cells store data corresponding to exponent fields of the plurality of binary numbers, and the plurality of addresses correspond to a plurality of faulty cells,
wherein the selection circuit is further configured to output the fault address of a first faulty cell in a plurality of faulty cell, wherein the first faulty cell has a first priority in a cell replacement operation and has a stuck-at-1 fault in a bit in the exponent field of a first binary number of the plurality of binary numbers;
a replacement circuit configured to replace, according to the fault address, the first faulty cell with a redundant cell of a plurality of redundant cells; and
a clipping circuit configured to output to the neural network processor a first threshold value when the first binary number is greater than the first threshold value.
