1. An uncommitted memory identifier apparatus for identify uncommitted memory blocks in a memory device during an initialization procedure, the apparatus comprising:

  • a test pattern identifier, coupled to read a first memory block within a system SRAM, that identifies a test pattern in the first memory block;

    a comparator, coupled to the test pattern identifier and coupled to read a second memory block contiguous to the first memory block, that compares the test pattern to a second pattern read from the second memory block to identify if the test pattern is repeating; and

    an uncommitted memory boundary identifier, coupled to the comparator, that defines start and end boundaries of an uncommitted memory space based on the comparison of the test pattern to the second pattern and at least one user-defined limit applied to the analysis of the system SRAM.
