SEMICONDUCTOR MEMORY DEVICE AND MEMORY SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 17659475 titled 'SEMICONDUCTOR MEMORY DEVICE AND MEMORY SYSTEM
Simplified Explanation
The patent application describes a semiconductor memory device that includes a memory cell array and a control logic circuit. The control logic circuit has a mode register and a remaining lifetime calculating device. The remaining lifetime calculating device counts usage metrics such as the number of clock signals received, the amount of data transmitted or received, and the number of commands received from a memory controller. It then generates a remaining lifetime code based on these metrics and stores it in the mode register.
- The semiconductor memory device includes a memory cell array and a control logic circuit.
- The control logic circuit has a mode register and a remaining lifetime calculating device.
- The remaining lifetime calculating device counts usage metrics such as the number of clock signals received, the amount of data transmitted or received, and the number of commands received from a memory controller.
- It generates a remaining lifetime code based on these metrics.
- The remaining lifetime code is stored in the mode register.
Potential Applications
- This technology can be used in various semiconductor memory devices such as RAM, flash memory, and solid-state drives.
- It can be applied in computer systems, mobile devices, and other electronic devices that use semiconductor memory.
Problems Solved
- The technology solves the problem of not knowing the remaining lifetime of a semiconductor memory device.
- By counting usage metrics and generating a remaining lifetime code, it provides a way to estimate the remaining lifespan of the device.
- This information can be used for proactive maintenance, data backup, and replacement planning.
Benefits
- The technology allows for better management and optimization of semiconductor memory devices.
- It enables users to monitor the health and remaining lifespan of their memory devices.
- By providing a remaining lifetime code, it helps prevent unexpected failures and data loss.
- It can extend the overall lifespan and reliability of semiconductor memory devices.
Original Abstract Submitted
A semiconductor memory device includes a mammy cell array including a plurality of memory cells and a control logic circuit configured to control the semiconductor memory device, The control logic circuit includes a mode register and a remaining lifetime calculating device configured to count usage metrics based on one or more of the following: a number of clock signals received from a memory controller, an amount of data transmitted or received to or from the memory controller, and/or a number of commands received from the memory controller. The remaining lifetime calculating device generates a remaining lifetime code representing a remaining lifetime of the semiconductor memory device based on the usage metrics, and stores the remaining lifetime code in the mode register.
