Abstract
A memory controller includes a command scheduler, a timer and an interface configured to transmit memory access commands, including primary and secondary precursor memory access commands, to a memory. The command scheduler selects memory access commands associated with memory access requests. The timer indicates expiration of first and second time periods. The first time period is shorter than the second time period by a designated amount and the second time period is greater than or equal to a minimum time between a prior memory access command and a secondary precursor memory access command for the memory. The command scheduler allows selection of a primary precursor memory access command when the first time period has expired and allows selection of a secondary precursor memory access command when the second time period has expired.
