Abstract
A disclosed apparatus to access a nonvolatile memory includes a physical geometry selector to select a first assumed physical geometry of a nonvolatile memory from among a plurality of assumed physical geometries supported by a memory controller, an information supplier to supply information about the first physical geometry to a set of registers, and a boot up controller to cause the memory controller to access data in the nonvolatile memory. The memory controller to access data in the nonvolatile memory uses the information supplied to the set of registers. Example disclosed apparatus further include a feedback input to receive feedback from the memory controller.
Claims20
An apparatus to access a nonvolatile memory, the apparatus comprising:
- a physical geometry selector to select a first assumed physical geometry of a nonvolatile memory from among a plurality of assumed physical geometries supported by a memory controller;
- an information supplier to supply information about the first physical geometry to a set of registers;
- a boot up controller to cause the memory controller to access data in the nonvolatile memory, the memory controller to access data in the nonvolatile memory using the information supplied to the set of registers;
- and
- a feedback input to receive feedback from the memory controller.
At least one tangible machine readable medium comprising instructions, the instructions, when executed, to cause the machine to at least:
- supply first information identifying a first assumed physical geometry of a nonvolatile memory to a memory controller;
- cause the memory controller to read a first chunk of data from the nonvolatile memory;
- responsive to a first input signal, supply second information identifying a second assumed physical geometry of the nonvolatile memory to the memory interface;
- and
- responsive to a second input signal, cause the memory controller to read additional chunks of data from the nonvolatile memory based on the first assumed physical geometry.
A method to read from a nonvolatile memory, the method comprising:
- supplying first information identifying a first assumed physical geometry of the nonvolatile memory to a memory controller;
- causing the memory controller to read data stored on the nonvolatile memory based on the first assumed physical geometry of the nonvolatile memory;
- and
- in response to an input indicating an error occurred when the memory controller read the nonvolatile memory, supplying second information identifying a second assumed physical geometry to the memory controller.
