Abstract:
A nonvolatile memory device includes a nonvolatile memory cell array including a plurality of nonvolatile memory cells connected to a plurality of word lines, a word line voltage generator configured to generate first and second sequences of voltage pulses. The device selectively supplies one of the first and second sequences of voltage pulses to a selected one of the word lines to program the nonvolatile memory cells connected to the selected word line. A slope of at least one voltage pulse of the first sequence of voltage pulses is greater than a slope of at least one voltage pulse of the second sequence of voltage pulses. In general, the first sequence is applied to word lines far away from the string select line (SSL), and the second sequence is applied to word lines that are close to the SSL.
Abstract:
A method of forming a semiconductor device includes forming a three-dimensional structure formed of a semiconductor on a semiconductor substrate, and isotropically doping the three-dimensional structure by performing a plasma doping process using a first source gas and a second source gas. The first source gas includes n-type or p-type impurity elements, and the second source gas includes a dilution element regardless of the electrical characteristic of a doped region.
Abstract:
A flash memory device comprising a high voltage generator circuit that is adapted to supply a program voltage having a target voltage to a selected word line is provided. The flash memory device is adapted to terminate the program interval in accordance with when the program voltage has been restored to the target voltage after dropping below the target voltage. A method for operating the flash memory device is also provided.
Abstract:
Disclosed is a flash memory device and a program verification method thereof which can prevent a misjudgment as to whether flash memory cells are programmed or not. The flash memory device includes: a program verification voltage generator for variably generating program verification voltages used to verify whether the flash memory cells are programmed or not and a word line level selector for transferring the program verification voltages to word lines connected to control gates of the flash memory cells. The flash memory cells that are verified as uncertain as to whether the flash memory cells are programmed or not can be completely programmed since the program verification operation is carried out with program verification voltage levels that are changed according to the selective activations of the program verification control signals.
Abstract:
A semiconductor device includes a gate pattern disposed on a semiconductor substrate, a gate spacer disposed on both sidewalls of the gate pattern, and a fixed charge layer disposed in the semiconductor substrate below the gate spacer. Elements generating fixed charges are injected into the fixed charge layer. A layer in which carriers induced by the fixed charge layer are accumulated is disposed below the fixed charge layer. The elements are segregated to a substrate of the semiconductor substrate from the inside of the semiconductor substrate by heat.
