Plastic conductive particles having an outer diameter of 2.5 μm˜1 mm obtained by sequentially plating a 0.1˜10 μm thick metal plating layer and a 1˜100 μm thick Pb solder layer or a Pb-free solder layer on plastic core beads having a high elastic modulus of compression, and a method of manufacturing thereof. The method of manufacturing the plastic conductive particles includes preparing plastic core beads having excellent thermal properties and a high elastic modulus of compression, etching surfaces of the plastic core beads for surface treatment thereof, forming a metal plating layer via electroless plating to improve adhesion between the bead surface and the metal plating layer, and then forming a solder layer such that a sealed hexagonal barrel is immersed in an electroplating solution and then an electroplating process is conducted using a mesh barrel rotating 360° at 6˜10 rpm or a mesh barrel having a structure in which one surface of a conventional sealed hexagonal barrel is open, and rotating 200° in right and left directions at 1˜5 rpm, to manufacture plastic conductive particles having a size of 1 mm or less. The plastic conductive particles of this invention enable the maintenance of packaging gaps, and thus can be applied to IC packaging, LCD packaging and other conductive materials.

Disclosed is a page buffer having a wired-OR type structure and a cache function which is adapted for use in a nonvolatile semiconductor memory device and a method of programming same. The page buffer embeds the cache latch block in relation to the cache function. Moreover, the nonvolatile semiconductor memory device includes an output driver enabling an internal output line to be unidirectional driven, thereby enabling a program-verifying operation using the wired-OR scheme.

A programming method for a nonvolatile memory device includes performing a LSB programming operation programming all LSB logical pages, and thereafter performing a MSB programming operation programming all MSB logical pages, wherein during the LSB programming operation a selected MLC is programmed to a negative intermediate program state. A program sequence for the LSB and MSB programming operations may be sequential or non-sequential in relation to an order arranged of word lines.

According to one aspect, a memory cell array includes a bit line connected to a plurality of nonvolatile memory cells, where the nonvolatile memory cells are selectively programmable in any one of at least first, second, third and fourth threshold voltage states, and where the first, second, third and fourth threshold voltage states correspond to four different data values defined by first and second bits. A page buffer circuit stores a logic value as main latch data and is responsive to a main latch signal to selectively flip the logic value of the main latch data according to a voltage level of the bit line. A sub-latch circuit stores a logic value as sub-latch data and is responsive to a sub-latch signal to selectively flip the logic value of the sub-latch data according to the voltage level of the bit line. The memory device is operable in a read mode which reads the threshold voltage state of the non-volatile memory cells and a programming mode which programs the threshold voltage state of the non-volatile memory cells, wherein the page buffer circuit is selectively responsive to the sub-latch data to inhibit flipping of the logic value of the main latch data in the programming mode.

A method for forming a defective pad repair structure in a liquid crystal display device having a plurality of pads disposed on a substrate. At least one defective pad repair line is provided to oppose the pads with an insulating layer disposed between the pads and the defective pad repair line. When at least one of the pads is broken, the broken pad can be restored by connecting the broken pad to the repair line by a welding process.

摘要:
A method and apparatus for controlling two or more non-volatile memory devices includes activating a read enable signal or a write enable signal, which is input to the first and second non-volatile memory devices, using a controller. A first chip enable signal is alternately activated for selecting the first non-volatile memory device and a second chip enable signal is activated for selecting the second non-volatile memory device using the controller. This is done while the read enable signal or the write enable signal is input to the first and second non-volatile memory devices being activated. Accordingly, even when the minimum cycle of the controller is longer than that of a memory device read/write time is reduced, thereby improving read/write performance.
