Abstract
Embodiments of the invention take advantage of an unused state of an interface protocol (or specification), such as the ONFI specification, to control a selector circuit to assert one of a plurality of relatively localized device selection signals (e.g., chip enable signals).
Claims15
An apparatus, comprising:
- a selector circuit to provide within a module a selected one of a plurality of die selection signals within the module in response to receiving an otherwise previously unused combination of instruction control signals from an interface specification.
An apparatus, comprising:
- a solid state drive having:
- a NAND flash module having a plurality of NAND flash chips, each chip with an associated chip enable input;
- a controller within the drive to write data into and read data from the drive;
- and
- a selector circuit to select one of the chip enable inputs in response to receiving an otherwise unused combination of instruction control signals.
