Samsung patents memory chip that double-checks data security before saving

Patent drawing
Patent drawing from the official filing.

Samsung has been granted a patent for a memory device that verifies data before storing it. The chip uses a processor to create two separate security codes at different times and compares them against a standard code to ensure the data is valid.

Why it mattersThis adds an extra layer of security to how data is saved in devices, helping prevent corrupted or tampered information from being stored.

In the filing’s own words

A memory device may include a memory block and a processor. The processor may be configured to identify data, identify a standard authentication code corresponding to the data, generate a first comparison authentication code corresponding to the data using a hash key, generate a second comparison authentication code corresponding to the data using the hash key at a different time than the first comparison authentication code, and identify whether to store the data in the memory block based on at least one of the first comparison authentication code and the second comparison authentication code, and the standard authentication code.

What exactly they claim (claim 1)

1. A memory device comprising: a memory block; and a processor configured to: identify data received from an external host, identify a standard authentication code corresponding to the data and the standard authentication code being received from the external host, generate a first comparison authentication code corresponding to the data using a hash key, generate a second comparison authentication code corresponding to the data using the hash key at a different time than the first comparison authentication code, and identify whether to store the data in the memory block based on at least one of the first comparison authentication code and the second comparison authentication code, and the standard authentication code.
