Abstract
A non-volatile memory (NVM) device includes an NVM array, which is configured to store data, and control logic. The control logic is configured to receive data values for storage in the NVM array, and to write at least some of the received data values to the NVM array and simultaneously to write complements of the at least some of the received data values.
Claims22
A non-volatile memory (NVM) device, comprising:
- an NVM array which is configured to store data;
- and
- control logic, which is configured to receive data values for storage in the NVM array, and to write at least some of the received data values to the NVM array and simultaneously to write complements of the at least some of the received data values.
A non-volatile memory (NVM) device, comprising:
- an NVM array which is configured to store data;
- and
- control logic, which is configured to receive data values for storage in the NVM array, and to write one only of at least some of the received data values and complements of the at least some of the received data values to the NVM array.
