  • Semiconductor memory and method for operating the same
    Patent number: 7203115
    Abstract: A data additional circuit adds plural types of expectation data to be read from a refresh block to data read from other blocks, respectively, to generate plural read data strings. An error correction circuit detects errors for each read data string, and sets the most reliable result of the error detection results to be true. The error correction circuit decodes data to be read from the refresh block based on a true error detection result. Moreover, the error correction circuit corrects the error of the read data string corresponding to the true error detection result. Consequently, without extending the read cycle time, a refresh operation can be hid, and errors can be corrected simultaneously. By correcting a data error read from a bad memory cell of data retention characteristics, a refresh request interval can be extended, and power consumption during a standby period can be reduced.

  • Semiconductor memory which performs the refresh operation internally and automatically without refresh commands from the exterior
    Patent number: 7203114
    Abstract: An oscillator generates a refresh request signal periodically. A storing circuit changes a stored value by a predetermined value in response to the refresh request signal and returns the stored value by one in response to a refresh operation. A store control circuit, when a state detecting circuit detects a change of an operational state of a semiconductor memory, increases or decreases the predetermined value which the storing circuit uses. A refresh decision circuit outputs refresh signals of a number corresponding to the stored value until the stored value returns to an initial value. This makes it possible to change the frequency of the refresh operations according to a change of the operational state without changing an oscillation cycle of the oscillator. Without unnecessary oscillation of the oscillator, it is possible to decrease a standby current of the semiconductor memory.
