Encrypted gang programming

Abstract

Disclosed are apparatus and methods for programming a plurality of nonvolatile memory (NVM) devices. Each NVM device self-generates and stores a unique encryption key. Each NVM device concurrently receives an image from a multiple-device programming system to which all the NVM devices are communicatively coupled. Each NVM device encrypts the received image using such NVM device's unique encryption key to produce a unique encrypted image for each NVM device. Each NVM device stores its unique encrypted image within a nonvolatile memory of such NVM device. The unique encryption key can then be securely transferred to a host device for decrypting the image accessed from one of the NVM devices.

Dependencies are inferred from the claim text.
