Disabling a command associated with a memory device

TL;DR: In this article, a memory device may contain device processing logic and a mode register, a register that may specify a mode of operation of the memory device, and a field in the mode register may hold a value that may indicate whether a command associated with the memory devices is disabled.

Abstract: In an embodiment, a memory device may contain device processing logic and a mode register. The mode register may a register that may specify a mode of operation of the memory device. A field in the mode register may hold a value that may indicate whether a command associated with the memory device is disabled. The value may be held in the field until either the memory device is power-cycled or reset. The device processing logic may acquire an instance of the command. The device processing logic may determine whether the command is disabled based on the value held by the mode register. The device processing logic may not execute the instance of the command if the device processing logic determines the command is disabled. If the device processing logic determines the command is not disabled, the device processing logic may execute the instance of the command.
