MEMORY DEVICE AND REFRESH METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 18197084 titled 'MEMORY DEVICE AND REFRESH METHOD THEREOF
Simplified Explanation
The patent application describes a memory device with counters, a refresh control circuit, a queue, and flags.
- The memory device has counters that keep track of the number of accesses to each row.
- A refresh control circuit changes a flag every refresh period and determines whether to put an incoming row address into a queue.
- The decision to put the row address into the queue is based on the count value of the corresponding counter, the value of a first flag, and the value of the second flag set in the current refresh period.
Potential applications of this technology:
- Memory devices in computer systems and electronic devices.
- Any application that requires efficient memory management and refresh control.
Problems solved by this technology:
- Efficient management of memory access and refresh operations.
- Preventing data loss or corruption due to insufficient refresh cycles.
Benefits of this technology:
- Improved memory performance and reliability.
- Reduced power consumption by optimizing refresh operations.
Original Abstract Submitted
A memory device may include counters respectively corresponding to rows and each configured to count a number of accesses to a corresponding row, a refresh control circuit, a queue, and first flags respectively corresponding to the rows. The refresh control circuit may change a second flag set in a refresh period every refresh period, and determine whether to put an incoming row address into the queue based on a count value of a counter corresponding to a target row indicated by the incoming row address among the counters, a first flag value of a first flag corresponding to the target row among the first flags, and a second flag value of the second flag set in a current refresh period.
