READING A MASTER BOOT RECORD FOR A NAMESPACE USING A REGULAR READ OPERATION - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 17726436 Titled 'READING A MASTER BOOT RECORD FOR A NAMESPACE USING A REGULAR READ OPERATION'
Simplified Explanation
This abstract describes a system for managing memory devices, specifically NAND flash memory in a solid-state drive. The memory is divided into different sections called namespaces, and one of these namespaces is allocated for use by a host device. The controller of the memory writes master boot record (MBR) data to a specific region assigned to the namespace. When the host device sends read commands for addresses within the namespace, the read circuitry can retrieve either user data or MBR data. This retrieval is done using a regular read operation by the controller, without triggering any hardware exceptions that would slow down the processing by the controller's firmware.
Original Abstract Submitted
Systems, methods, and apparatus related to memory devices. In one approach, a memory (e.g., NAND flash memory of a solid-state drive) is allocated to a namespace for use by a host device. Master boot record (MBR) data is written by a controller of the memory to an MBR region assigned to the namespace. Read circuitry is configured to read either of user data or MBR data in response to read commands received from the host device for addresses in the namespace. The user data or the MBR data is read using a regular read operation of the controller (e.g., without triggering any hardware exceptions that require significantly slower processing by firmware of the controller).
