| 20100325347 | APPARATUS FOR CONTROLLING NAND FLASH MEMORY - Provided is an apparatus for controlling NAND flash memory. The apparatus for controlling NAND flash memory includes: a register unit in which a start address of a macro-command to be executed, selected from macro-commands included in a command script in which at least one macro-command in which a plurality of micro-commands for controlling a unit operation of NAND flash memory are arranged in an array shape, is described, is recorded; a command fetch unit, if a start address of the macro-command to be executed is recorded in the register unit, accessing first memory connected based on the start address of the macro-command to be executed and sequentially reading the plurality of micro-commands from the start address of the macro-command to be executed; a command interpretation unit interpreting the read micro-commands and outputting the result of interpretation including types of the micro-commands and command parameters; and a command execution unit generating interface signals for controlling an operation of NAND flash memory according to each of the micro-commands based on the result of interpretation. Time required for data transmission and NAND flash control can be reduced, and a high performance can be obtained. | 12-23-2010 |
