Claim:
A portable flash memory device, comprising: a housing having a top cover and a bottom cover, wherein the top cover includes a top opening disposed thereon; and a core unit having a universal serial bus (USB) plug connector coupled to one or more multi-level cell (MLC) flash memory devices and an MLC flash controller disposed therein, the MLC flash controller controlling the one or more MLC flash memory devices and the USB plug connector providing an interface for accessing the one or more MLC flash memory devices, wherein the core unit includes a chip-on-bard (COB) package having the MLC flash memory devices and MLC flash controller embedded therein, a COB carrier having a COB compartment for storing the COB package therein, wherein the COB carrier includes a top surface having a slide button disposed thereon, and a metal cover to allow a frontend of the COB carrier having USB compatible electrical contact pins disposed therein, wherein the frontend of the COB carrier slides into the metal cover to form the USB plug connector, wherein the housing is configured to enclose, using the top cover and the bottom cover, the core unit by exposing the slide button through the top opening of the housing, wherein the slide button, when being pushed sliding forward within the top opening of the housing, causes the USB plug connector of the core unit to be deployed external to the housing through a front opening of the housing, and wherein the slide button, when being pushed sliding backward within the top opening of the housing, causes the USB plug connector of the core unit to be retracted into the housing through the front opening of the housing.
