Abstract
Provided is a memory device comprising a circuit assembly including a flexible substrate and at least one flash memory chip mounted thereupon. The flexible substrate has upper and lower surfaces and a flash memory chip is preferably mounted on at least one the upper and lower surfaces. The flash memory chip may be configured as one of a thin small outline package (TSOP) package device, a very very small outline package (WSOP) package device, and a chip on board (COB) device. The memory device may further comprise a hollow housing body having a hollow interior compartment sized and configured to receive the circuit assembly therewithin. A universal series bus (USB) connector may be mounted on a free end of the flexible substrate and is preferably configured to electrically connect the memory device to an electric device.

A memory device, comprising:
- a circuit assembly oriented to be in an unfolded state and a folded state and including:
- a flexible substrate having an elongate main portion and a wing portion extending laterally outwardly therefrom, the elongate main portion remaining unfolded when the circuit assembly is oriented in the folded state;
- a controller mounted on the elongate main portion;
- at least one passive component mounted on the elongate main portion;
- at least one flash memory chip mounted on the elongate main portion;
- at least another one flash memory chip mounted on the wing portion;
- wherein the wing portion being foldable over the elongate main portion when the circuit assembly is oriented in the folded state, the wing portion being foldable over an area of the elongate main portion where the controller and the at least one passive component are not vertically adjacent to the at least one wing portion flash memory chip;
- and
- the memory device further comprising a hollow housing body having a proximal end and a distal end and being open on the proximal end, the housing body defining an interior compartment sized and configured to receive the circuit assembly thereinto.
A memory device, comprising:
- a circuit assembly oriented to be in an unfolded state and a folded state and including:
- a flexible substrate having an elongate main portion and a wing portion extending laterally outwardly therefrom, the elongate main portion being unfolded when the circuit assembly is oriented in the folded state;
- a controller mounted on the elongate main portion;
- at least one passive component mounted on the elongate main portion;
- and
- a pair of flash memory chips mounted in side-by-side arrangement on the elongate main portion;
- at least one flash memory chip mounted on the wing portion;
- wherein the circuit assembly assumes the folded state when the flexible substrate is at least partially folded over itself, the wing portion being foldable over an area of the elongate main portion where the controller and the at least one passive components are not vertically adjacent to the at least one wing portion flash memory chip;
- and
- the memory device further comprising a hollow housing body having a proximal end and a distal end and being open on the proximal end, the housing body defining an interior compartment sized and configured to receive the circuit assembly thereinto.
