A memory controller includes a command scheduler, a timer, and an interface configured to send memory access commands including a primary predecessor memory access command and a secondary predecessor memory access command to a memory. The command scheduler selects a memory access command associated with a memory access request. The timer indicates expiration of the first time period and the second time period. The first time period is shorter than the second time period by a specified amount, and the second time period is greater than or equal to a minimum time between a previous memory access command and an auxiliary predecessor memory access command of the memory. The command scheduler allows selection of a primary predecessor memory access command when the first time period has expired, and allows selection of a secondary predecessor memory access command when the second time period has expired.

A memory controller combines information about which memory component segments are not being refreshed with the information about which rows are going to be refreshed next, to determine, for the current refresh command, the total number of rows that are going to be refreshed. Based on this total number of rows, the memory controller selects how long to wait after the refresh command before issuing a next subsequent command. When the combination of masked segments and the refresh scheme results in less than the ‘nominal’ number of rows typically refreshed in response to a single refresh command, the waiting period before the next command (e.g., non-refresh command) is issued may be reduced from the ‘nominal’ minimum time period, thereby allowing the next command to be issued earlier.
