Abstract
A memory includes memory cells arranged in rows and in columns, with at least one bit line for each column being coupled to the memory cells of the column. A read/write circuit is coupled to the bit lines and is configured to receive, for each column, a binary datum to be stored in one of the memory cells of the column. The read/write circuit includes, for each column, a latch configured to store a bit of a key, and an encryption circuit configured to encrypt the received binary datum with the bit of the key to provide encrypted binary datum. The read/write circuit controls the bit line to thereby store the encrypted binary datum.
