Methods for a random read and read/write block accessible memory

摘要

In one embodiment of the invention, a memory apparatus is disclosed. The memory apparatus includes a memory array, a block read/write controller, and a random access read memory controller. The memory array is block read/write accessible and random read accessible. The block read/write controller is coupled between the memory array and an external interconnect. The block read/write controller performs block read/write operations upon the memory array to access blocks of consecutive memory locations therein. The random access read memory controller is coupled between the memory array and the external interconnect in parallel with the block read/write access controller. The random access read memory controller performs random read memory operations upon the memory array to access random memory locations therein.

1. A method comprising:
mapping, with a controller, addresses of a disk-read-only-memory (disk-ROM) into a processor address space, the disk-ROM including a memory that is writeable with a disk-like write access and readable with both a disk-like read access and a random read access; writing data into memory locations of the disk-ROM using a disk-like write access in response to the mapped addresses in the processor address space; and reading data from the memory locations of the disk-ROM using a random read access in response to the mapped addresses in the processor address space.
