Abstract
A memory controller is described. The memory controller includes a register to collectively track row active commands sent to multiple memory chip banks of a memory rank. The memory controller includes a filter circuit to prevent an activate count value that is to be maintained in the register from being incremented in response to a row activate command that is sent to a different bank than a prior row activate command that caused the activate count value to be incremented
