Nonvolatile memory bank groups

A method comprising:

• partitioning a nonvolatile memory (10) into bit addressable locations grouped in the banks (10);
• grouping the banks (20) into bank groups (24) based on a write-to-read latency of the nonvolatile memory (10), each bank group (20) having a dedicated state control machine (30).

An apparatus comprising:

• a nonvolatile memory (10) partitioned into bits grouped in the banks (20), the banks (20) organized as bank groups (24), each bank group (24) having a dedicated state control machine (30), wherein the memory (10) has a number of bank groups (24) exceeding the write-to-read latency of the nonvolatile memory (10), wherein the nonvolatile memory (10) has a write-to-read latency of at least 4:1, and wherein a majority of time to write to an individual bank (20) of one of the bank groups (24) is less than a time to read an individual bank (20) from each of the other bank groups (24);
• and
• a memory controller (202) configured to write to the individual bank (20) while concurrently reading or writing the individual bank (20) in each of the other bank groups (24).
