Solid state memory formatting

Abstract

The present disclosure includes methods and devices for solid state drive formatting. One device embodiment includes control circuitry coupled to a number of memory arrays, wherein each memory array has multiple physical blocks of memory cells. The memory arrays are formatted by the control circuitry that is configured to write system data to the number of memory arrays, where the system data ends at a physical block boundary; and write user data to the number of memory arrays, where the user data starts at a physical block boundary.
