摘要:
A method of programming a nonvolatile memory device comprises counting a number of state pairs in a unit of input data, modulating the unit of input data to reduce the number of state pairs contained therein, and programming the modulated unit of input data in the nonvolatile memory device. Each state pair comprises data with a first state and designated for programming in a memory cell connected to a first word line, and data with a second state and designated for programming in a memory cell connected to a second word line adjacent to the first word line. The memory cell connected to the first word line is adjacent to the memory cell connected to the second word line.

A method of encoding multi-bit level data includes: determining a range of an error pattern generated according to a transmission symbol, encoding an M-bit level of a P-bit level corresponding to the transmission symbol based on the range of the error pattern, and excluding encoding of a P-M bit level of the P-bit level. The variable P is a natural number of a value at least two, and the variable M is a natural number less than P.

An apparatus and a method for reading from a non-volatile memory whereby soft decision data is used to determine the reliability of hard decision data. The hard decision data read from the non-volatile memory is de-randomized and the soft decision data read from the non-volatile memory is not de-randomized. Using the soft decision data, the hard decision data is decoded.

A memory system comprises a non-volatile memory device that stores user data and state information regarding the user data. In a read operation of the non-volatile memory device, a memory controller calculates a priori probabilities for the user data based on the state information, calculates a posteriori probabilities based on the a priori probabilities, and performs a soft-decision operation to determine values of the user data based on the a posteriori probabilities.

An analog delay element for delaying an input clock signal to produce an output clock signal. The analog delay element includes a delay circuit for receiving the input clock signal and for providing an intermediate clock signal in response to a first bias voltage. A current mirror amplifier generates a first current in a first current branch in response to the intermediate clock signal, and generates a second current in a second current branch in response to the first current and a second bias voltage. The second current branch has an output node for providing the output clock signal having a logic level corresponding to the delayed intermediate clock signal logic level.

A regulator circuit is provided for use with cell plate voltage generators of memory cell capacitors and precharge bit lines voltage generators in semiconductor memories. The circuit employs a current source coupled to the charging reference voltage whose output is controlled by a level detector, which receives as input a reference level signal and the cell plate voltage. When the cell plate voltage drops below the reference level, the level detector triggers the current source, thereby recovering the cell plate voltage to the reference level. The level detector can be disabled through an input.
