Embodiment Construction

[0016] The present disclosure encompasses devices, methods, and systems for blockchain-based verification of memory commands. Embodiments include: a memory; and circuitry configured to: receive a command included in a block in a chain of blocks for verifying a command to be executed on the memory, wherein the command includes a command based on the anti-replaying a portion of a previous command in a previous block in a chain of blocks; validating the command using the anti-replaying portion of the command; and executing the command on the memory after validating the command.

[0017] Many threats may affect the operation of memory (eg, a memory device) and / or data stored therein (eg, data stored in memory cells of a memory device). For example, a hacker or other malicious user may attempt to perform an activity (eg, an attack), such as a man-in-the-middle (MITM) attack, to make unauthorized changes to the operation of the memory and / or to data stored therein for malicious purp...

Abstract

The present disclosure includes apparatuses, methods, and systems for block chain validation of memory commands. An embodiment includes a memory, and circuitry configured to receive a command that is included in a block in a block chain for validating commands to be executed on the memory, wherein the command includes an anti-replay portion that is based on a previous command included in a previous block in the block chain, validate the command using the anti-replay portion of the command, and execute the command on the memory upon validating the command.

Description

technical field [0001] The present disclosure relates generally to semiconductor memory and methods, and more specifically, to blockchain-based memory command verification. Background technique [0002] Memory devices are typically provided as internal semiconductor integrated circuits in computers or other electronic devices and / or as external removable devices. There are many different types of memory, including volatile and non-volatile memory. Volatile memory can require power to maintain its data and can include random access memory (RAM), dynamic random access memory (DRAM) and synchronous dynamic random access memory (SDRAM), among others. Non-volatile memory provides persistent data by preserving stored data when power is not applied, and can include NAND flash memory, NOR flash memory, read-only memory (ROM), and resistance variable memory, such as phase-change random Access memory (PCRAM), resistive random access memory (RRAM) and magnetic random access memory (M...
