MEMORY DEVICE HAVING AN IMPROVED ECC ARCHITECTURE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240221856 titled 'MEMORY DEVICE HAVING AN IMPROVED ECC ARCHITECTURE
The present disclosure pertains to a memory device with an array of memory cells and an operating circuit for managing the array's operation. The operating circuit includes an encoding unit that generates a codeword containing payload data stored in multiple memory cells, parity data stored in parity cells, and extra payload data in unused parity cells. A decoding unit performs error correction code (ECC) operations based on the selected ECC protection level.
- The memory device includes an encoding unit that generates a codeword with payload data, parity data, and extra payload data.
- The number of parity cells used is selectable based on the ECC protection level.
- The decoding unit performs ECC operations based on the selected protection level.
- Circuit portions in the encoding and decoding units are selectively activable based on the ECC protection level.
- Each circuit portion manages a predetermined payload and parity quantity of the codeword.
