Abstract
Methods of performing an internal diagnostic for a NAND configured memory device include storing data in a data cache coupled to an array of memory cells arranged in a NAND configuration, wherein the data stored in the data cache corresponds to at least one diagnostic function; performing a decode operation on the data stored in the data cache, wherein the decode operation generates a diagnostic function command for testing internal functions of the NAND configured memory device; and providing the decoded diagnostic function command to a state machine of the NAND configured memory device adapted to perform the decoded diagnostic function command.

A method of performing an internal diagnostic for a NAND configured memory device comprising:
- storing data in a data cache coupled to an array of memory cells arranged in a NAND configuration, wherein the data stored in the data cache corresponds to at least one diagnostic function;
- performing a decode operation on the data stored in the data cache, wherein the decode operation generates a diagnostic function command for testing internal functions of the NAND configured memory device;
- and
- providing the decoded diagnostic function command to a state machine of the NAND configured memory device adapted to perform the decoded diagnostic function command.
A method of performing an internal diagnostic for a NAND configured memory device comprising:
- performing a read operation on an array of memory cells of the NAND configured memory device, wherein data read during the read operation corresponds to at least one diagnostic function;
- storing the read data in a data cache coupled to the array of memory cells;
- performing a decode operation on the data stored in the data cache, wherein the decode operation generates a diagnostic function command for testing internal functions of the NAND configured memory device;
- and
- providing the decoded diagnostic function command to a state machine of the NAND configured memory device adapted to perform the decoded diagnostic function command.
A method of performing an internal diagnostic for a NAND configured memory device comprising:
- receiving data at an I/O port of the NAND configured memory device, wherein the data received at the I/O port corresponds to at least one diagnostic function;
- storing the received data in a data cache coupled to an array of memory cells arranged in a NAND configuration;
- performing a decode operation on the data stored in the data cache, wherein the decode operation generates a diagnostic function command for testing internal functions of the NAND configured memory device;
- and
- providing the decoded diagnostic function command to a state machine of the NAND configured memory device adapted to perform the decoded diagnostic function command.
