MEMORY SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18162275 titled 'MEMORY SYSTEM
Simplified Explanation
The abstract describes a patent application for a controller that manages the allocation of blocks in a non-volatile memory to different areas for data storage and retrieval. The controller uses different modes for each area, optimizing the use of memory cells based on the type of data being written. It also transcribes data between areas as needed.
- The controller assigns blocks to different areas in the memory based on their intended use.
- It utilizes different modes for each area to optimize data storage and retrieval.
- Data received from a host device is written to the designated area.
- Valid data written to certain areas is transcribed to another area for storage.

Original Abstract Submitted
A controller assigns a first plurality of blocks among a plurality of blocks provided in a non-volatile memory to a first area, assigns a second plurality of blocks to a second area, and assigns a third plurality of blocks to a third area. The controller uses each block assigned to the first area in a first mode, uses each block assigned to the second area in a second mode in which the number of bits of data written in each memory cell is larger than that in the first mode, and uses each block assigned to the third area in the first mode or the second mode. The controller writes data received from a host device to an area that corresponds to a designation from the host device out of the first area and the third area. The controller transcribes valid data written to the first area and the third area to the second area.
