  • Patent number: 6707740
    Abstract: A plurality of sense amplifiers amplify parallel read data from memory cells, respectively. At least one of read amplifiers for amplifying the amplified read data respectively has a higher drivability than those of the rest of the read amplifiers. A connection switching circuit connects the sense amplifiers to a predetermined read amplifier according to an address. Switching the read data to one another before the amplification by the read amplifiers allows read data to be first outputted in burst read operation to be amplified by the read amplifier whose drivability is always high. In the burst read operation, a data output circuit first outputs read data corresponding to the read amplifier whose drivability is high. This enables reductions in read operation time and power consumption, even in a semiconductor memory in which the output orders of read data are changeable according to addresses or operation modes.

  • Patent number: 6707714
    Abstract: A memory cell array of a NAND-type flash memory is divided into a first and second cell arrays, and, during a read operation, a first voltage is applied to non-selected word lines of the first cell array, and a second voltage lower than the first voltage is applied, to non-selected word lines of the second cell array. The first cell array has a comparatively large write operation frequency, and therefore readily assumes an over-programmed state as a result of repeated write operations, whereas the second cell array has a comparatively small write operation frequency, and it is therefore difficult for same to assume an over-programmed state. As a result, the first voltage is made high, such that read problems are avoided even if over-programming arises, and the second voltage is made low, such that a read disturb is suppressed and a data change is avoided.

  • Patent number: 6702584
    Abstract: A karaoke device with built-in microphone includes a main body microphone, and converts an audio signal from the microphone into audio data by an A/D converter, and writes the audio data into a ring buffer by mixing with the data already stored in the ring buffer. If an echo mode is set, a delay time constant (CD) corresponding to the echo mode is determined, and on the basis thereof, a size of the ring buffer is set. The data is read from the ring buffer, and is inputted in a sound channel. If a voice effect mode is set, a reproduction frequency constant (CF) corresponding to the voice effect mode is determined, and based thereon, an inclement value of a read pointer of the ring buffer is determined, and then, the data is read from an address indicated by the read pointer. When the read pointer reaches the delay time constant, the relevant constant is subtracted from the read pointer value.
