A split gate NAND flash memory structure is formed on a semiconductor substrate of a first conductivity type. The NAND structure comprises a first region of a second conductivity type in the substrate with a second region of the second conductivity type in the substrate, spaced apart from the first region. A continuous first channel region is defined between the first region and the second region. A plurality of floating gates are spaced apart from one another with each positioned over a separate portion of the channel region. A plurality of control gates are provided with each associated with and adjacent to a floating gate. Each control gate has two portions: a first portion over a portion of the channel region and a second portion over the associated floating gate and capacitively coupled thereto.

An apparatus for displaying a basic input output system (BIOS) power-on self-test (POST) code and a method thereof are provided. The apparatus includes a BIOS, a conversion module, and an output module. The BIOS is used for generating a POST code. The POST code is transmitted via a low pin count (LPC) interface. The conversion module receives the POST code and converts the POST code into a system management bus (SMBus) format. The output module is used for receiving and outputting the POST code transmitted by the conversion module. The output module is an SMBus interface.
