MEMORY DEVICE FOR INTERRUPTIBLE MEMORY REFRESH

摘要

A refresh command is received from a memory controller. An interruptible refresh containing multiple segment refreshes is initiated. The segment refreshes are separated by interrupt boundaries. A command is received before execution of a segment refresh. The first command is executed and execution of the first segment refresh is delayed at a first interrupt boundary. Alternatively, a first number of segment refreshes to execute is received from a memory controller. The received first number of segment refreshes is executed. A second number of segment refreshes to execute is received from a memory controller. The received second number of segment refreshes is executed. No segment refreshes are executed between the execution of the first number of segment refreshes and the execution of the second number of segment refreshes.

1. A method for refreshing a memory device performed by the memory device, the method comprising:
receiving a refresh command; initiating an interruptible refresh in response to the refresh command, the interruptible refresh comprising a plurality of segment refreshes, the plurality of segment refreshes separated by interrupt boundaries; receiving a first command before execution of a first segment refresh; and executing the first command and delaying execution of the first segment refresh at a first interrupt boundary.
