Multiple (e.g., two) hosts access a single memory channel (and/or device) via a memory controller. The single memory channel/device can support at most one access at a time. To reduce contention between the multiple hosts, the memory controller comprises multiple (e.g., two), independent, host ports. Each host port is associated with a write buffer(s) in the memory controller that stores write data at least until the memory controller writes the data to the memory channel. Data stored in a write buffer may be used to respond to memory access commands (e.g., reads or writes) on the ports without accessing the memory channel. In this manner, the hosts do not directly contend with each other for the single memory channel or the memory controller.
