Abstract
Systems, apparatuses, and methods for managing a non-power of two memory configuration are disclosed. A computing system includes at least one or more clients, a control unit, and a memory subsystem with a non-power of two number of active memory channels. The control unit reduces a ratio of the number of active memory channels over the total number of physical memory channels to a ratio of a first number to a second number. If a first subset of physical address bits of a received memory request are greater than or equal to the first number, the control unit calculates a third number which is equal to a second subset of physical address bits modulo the first number and the control unit uses a concatenation of the third number and a third subset of physical address bits to select a memory channel for issuing the received memory request.
