FLASH MEMORY DEVICE AND SMART CARD INCLUDING THE SAME

摘要

A flash memory device and a smart card including the same are provided to maintain constant current consumption regardless of the number of program data bits. A main cell array(3100) has main cells arranged in rows and columns. A dummy cell array(3700) has dummy cells arranged in the rows and columns. A first write buffer circuit(3400) drives selected memory cells of the main cell array in response to input data. A second write buffer circuit(3900) drives selected dummy cells of the dummy cell array in response to inverted data of the input data.
