Abstract

A refresh command is communicated to a memory device to initiate an interruptible refresh which contains multiple segment refreshes separated by interrupt boundaries. A command is communicated to the memory device before execution of a segment refresh and the segment refresh is delayed at an interrupt boundary. Alternatively, a first number of commands in a queue is determined. A first number of segment refreshes to execute is determined based on the first number of commands. The first number of segment refreshes to execute is communicated to the memory device to cause execution of the first number of segment refreshes. A second number of commands in the queue is determined. A second number of segment refreshes to execute is determined based on the second number of commands. The second number of segment refreshes to execute is communicated to the memory device to cause execution of the second number of segment refreshes.
