Abstract: A memory device may be configured to receive a command to access a block of memory that is one of multiple blocks of memory included in the memory device. The memory device may be configured to receive a cryptographic signature associated with the command. The memory device may be configured to enable or disable access to the block of memory based on the command and based on the cryptographic signature. The memory device may be capable of separately restricting access to each individual block of the multiple blocks.

Abstract: In some implementations, a memory device may resolve a set of latches of a NAND page buffer to a set of initialized values. The memory device may obtain a NAND page buffer initialized data set from the set of initialized values of the set of latches. The memory device may generate a security key using the NAND page buffer initialized data set.

Abstract: One embodiment describes a computing system that includes a boot device. The boot device includes nonvolatile memory that stores startup routine instructions and a first pointer, in which the first pointer identifies a first one or more memory addresses in the nonvolatile memory where at least a portion of the startup routine instructions are stored, and a microcontroller that retrieves the startup routine instructions from the nonvolatile memory using the first pointer and determines whether the startup routine instructions are corrupted before executing any portion of the startup routine instructions. The computing system further includes a central processor communicatively coupled to the boot device, in which the central processor executes the startup routine instructions to initialize the computing system when the microcontroller determines that the startup routine instructions are not corrupted.
