STORAGE DEVICES AND METHODS OF OPERATING STORAGE DEVICES - A simplified explanation of the abstract

This abstract first appeared for US patent application 17850723 titled 'STORAGE DEVICES AND METHODS OF OPERATING STORAGE DEVICES

Simplified Explanation

The patent application describes a storage device that includes a nonvolatile memory device and a storage controller. The nonvolatile memory device has two memory regions with different write speeds. The storage controller has an internal buffer and stores data from an external host in the first memory region based on priority.

• The storage device has a nonvolatile memory device with two memory regions of different write speeds.
• The storage controller includes an internal buffer and stores data from an external host in the first memory region based on priority.
• The storage controller performs a read operation-transfer operation to read pre-stored data in the first memory region and transfers it to the data input/output circuit of the nonvolatile memory device multiple times.
• The transferred data is then stored in the second memory region.

Potential applications of this technology:

• Data storage devices such as solid-state drives (SSDs) or memory cards.
• Embedded storage in smartphones, tablets, or other portable devices.
• Cloud storage systems or data centers.

Problems solved by this technology:

• Efficiently managing data storage and migration in a storage device with different write speeds.
• Prioritizing data storage based on importance or urgency.
• Optimizing the use of memory regions with different write speeds.

Benefits of this technology:

• Improved performance and efficiency in data storage and migration operations.
• Enhanced data management capabilities in storage devices.
• Better utilization of memory regions with different write speeds.

Original Abstract Submitted

A storage device includes a nonvolatile memory device and a storage controller. The nonvolatile memory device includes a first memory region having a first write speed and a second memory region having a second write speed different from the first write speed. The storage controller includes an internal buffer and stores data from an external host in the first memory region by priority in a first mode. The storage controller controls a data migration operation by performing a read operation-transfer operation to read a second data that is pre-stored in the first memory region by a first unit and to transfer the first unit of data to a data input/output (I/O) circuit of the nonvolatile memory device a plurality of times and by storing the second data transferred to the data I/O circuit in the second memory region.
