| 20080219082 | NONVOLATILE SEMICONDUCTOR MEMORY - Disclosed is a nonvolatile memory system including at least one nonvolatile memory each having a plurality of nonvolatile memory cells and a buffer memory; and a control device coupled to the nonvolatile memory. The control device is enabled to receive external data and to apply the data to the nonvolatile memory, and the nonvolatile memory is enabled to operate a program operation including storing the received data to the buffer memory and storing the data held in the buffer memory to ones of nonvolatile memory cells. Moreover, the control device is enabled to receive external data while the nonvolatile memory is operating in the program operation. Also, the buffer memory is capable of receiving a unit of data, equal to the data length of data to be stored at one time of the program operation, the data length being more than 1 byte. | 09-11-2008 |
| 20090016102 | NONVOLATILE SEMICONDUCTOR MEMORY DEVICE WHICH STORES MULTI-VALUE INFORMATION - To enable one non-volatile memory cell to store four-value information, three different kinds of threshold voltages are serially applied to a word line in a verify operation to execute a write operation, the threshold voltages of the memory cell are controlled, and two-value (one-bit) information corresponding to the four-value (two-bit) information to be written are synthesized by a write data conversion circuit for each of the write operations carried out three times. In this way, the four-value (two-bit) information are written into one memory cell, and the memory capacity of the memory cell can be increased. In the information read operation, three different kinds of voltages are applied to a word line, three kinds of two-value (one-bit) information so read out are synthesized by a read conversion circuit and the memory information of the memory cell are converted to the two-bit information. | 01-15-2009 |

| 20100277996 | SEMICONDUCTOR DEVICE - A sense amplifier capable of performing high-speed data sense operation with lower power consumption using a minuscule signal from a memory cell even in a case where a memory array voltage is reduced. A plurality of drive switches for over-driving are distributively arranged in a sense amplifier area, and a plurality of drive switches for restore operation are concentratively disposed at one end of a row of the sense amplifiers. A potential for over-driving is supplied using a meshed power line circuit. Through the use of the drive switches for over-driving, initial sense operation can be performed on data line pairs with a voltage having an amplitude larger than a data-line amplitude, allowing implementation of high-speed sense operation. The distributed arrangement of the drive switched for over-driving makes it possible to dispersively supply current in sense operation, thereby reducing a difference in sense voltage with respect to far and near positions of the sense amplifiers. | 11-04-2010 |
