System and method for managing data access in non-volatile memory

A method of managing data access to a non-volatile solid-state memory array comprising units of memory accessible via one or more data channels, the method comprising:

• maintaining, in a controller for the memory array, an assignment table comprising information related to a memory access configuration that:
• groups a plurality of physical addresses in the memory array into a plurality of logical groups with the physical addresses for each logical group organized in a sequence, and
• associates a physical address number to each physical address, the physical address number corresponding to the position of the physical address in the sequence,
• wherein the physical addresses in each logical group are distributed across the units of memory accessible via the one or more data channels to maximize concurrent access to the memory array;
• receiving, in a controller, a memory command from a host system for execution in the memory array, the memory command associated with one or more logical addresses;
• in response to the memory command, determining, by the controller, one or more physical addresses for the memory command by using the assignment table;
• and
• executing, by the controller, the memory command in accordance with the one or more determined physical addresses,
• wherein physical address numbers for each of the plurality of logical groups are assigned to physical addresses that are accessible via different data channels on a rotating basis.
