MEMORY SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18458755 titled 'MEMORY SYSTEM
Simplified Explanation
The memory system described in the patent application includes a non-volatile memory and a memory controller that manages write, read, and erase operations based on commands from a host, as well as time information provided by the host to track when commands are issued. The memory controller uses this time information to generate history data reflecting the busy state of the memory system over specific time ranges, and triggers maintenance operations on the non-volatile memory based on the timing of commands received from the host.
- Memory system with non-volatile memory and memory controller
- Controller performs write, read, and erase operations based on host commands
- Time information from host used to track command timing and generate history data

Are there any limitations to the size or type of non-volatile memory that can be used with this technology?
The patent abstract does not specify any limitations regarding the size or type of non-volatile memory compatible with this technology. It would be important to understand if certain memory types or sizes are more suitable for implementation.
Original Abstract Submitted
A memory system includes a non-volatile memory and a memory controller. The memory controller is configured to perform write, read, and erase operations in accordance with write commands, read commands, and erase commands, respectively, from a host, and receive, from the host, time information indicating times when the write, read, and erase commands have been transmitted from or issued by the host. The memory controller is further configured to generate, from the received time information, history data including a value representing a busy state of the memory system with respect to each time range in a predetermined time period, and perform a maintenance operation with respect to the non-volatile memory upon time at which a command received from the host has been transmitted from or issued by the host falling in one or more of the time ranges corresponding to values smaller than the other of the time ranges.
