Abstract
Embodiments herein provide for avoiding address collisions in a memory device. In one embodiment, a memory controller includes a command scheduler operable to process a read-modify-write I/O command to a location in memory, to detect another I/O command to the same memory location while the read-modify-write I/O command is accessing the memory location, and to stall the other I/O command until the read-modify-write I/O command is complete while allowing a third I/O command to access the memory.
