STORAGE DEVICE INCLUDING NONVOLATILE MEMORY DEVICE AND OPERATING METHOD OF STORAGE DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18238282 titled 'STORAGE DEVICE INCLUDING NONVOLATILE MEMORY DEVICE AND OPERATING METHOD OF STORAGE DEVICE
Simplified Explanation
The patent application describes a storage device with a nonvolatile memory device and a controller that manages data allocation and retrieval efficiently.
- Nonvolatile memory device with multiple memory cells
- Controller with internal buffer containing zone buffers
- Allocates zones to storage space and assigns erase units based on zone map table
- Manages logical addresses of data in zones sequentially for efficient data retrieval
- Reads first data for sequential logical addresses requested by external host device
- Performs prefetch operation by reading second data for next sequential logical addresses and storing in internal buffer
- Improves data retrieval speed without waiting for next read request from external host device
---
- Potential Applications
- Data storage devices
- Solid-state drives
- Embedded systems
- Problems Solved
- Efficient data management and retrieval
- Faster data access for external host devices
- Improved performance of storage devices
- Benefits
- Faster data retrieval speed
- Efficient use of storage space
- Enhanced performance of storage devices
Original Abstract Submitted
A storage device, including: a nonvolatile memory device including a plurality of memory cells; and a controller including an internal buffer including zone buffers, and configured to: allocate a plurality of zones to a storage space, select two or more erase units to be allocated to each zone based on a zone map table, fixedly and sequentially manage logical addresses of data written in the plurality of zones, based on reads for sequential logical addresses being requested by the external host device, read first data corresponding to the sequential logical addresses from the nonvolatile memory device, and output the first data to the external host device, and based on the reads being requested, perform a prefetch operation by reading second data corresponding to next sequential logical addresses, and storing the second data in the internal buffer, without receiving a next read request from the external host device.
