MEMORY SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240094955 titled 'MEMORY SYSTEM

Simplified Explanation

The memory system described in the abstract 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. The memory controller uses this time information to generate history data reflecting the busy state of the memory system over specific time ranges within a predetermined period. Maintenance operations are then performed 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 and time information
• Generates history data to track memory system activity over time ranges
• Conducts maintenance operations on non-volatile memory based on command timing

The abstract does not specify the types of non-volatile memory that can be used with the described memory system, which could impact its compatibility and performance in different applications.

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.
