An integrated circuit includes a memory storage having bit cells, a write path switch configured to have a connection state determined by a reliability indicator, and a write driver having an input configured to receive an input data from a write terminal through either a first write path or a second write path. The input data received through the first write path is configured to be equal to the data at the write terminal, and the input data received through the second write path is configured to be a bitwise complement of the data at the write terminal. The reliability indicator is configured to be set based on a majority bit value in the data or based on a minority bit value in the data.

Non-volatile memory stored with encoded data

A method of storing a data into a memory storage having bit cells. The method includes identifying each of the binary one and the binary zero in the data as either a majority bit value or a minority bit value based on the probability of finding the binary one in the data or based on the probability of finding the binary zero in the data. In the method, a bit of the data is stored into the bit cell as the more preferred state if the bit of the data has the majority bit value, and a bit of the data is stored into the bit cell as the less preferred state if the bit of the data has the minority bit value.
