    • According to one embodiment, there is provided an information recording device that records information on a magnetic disk using a magnetic head. The registering module registers position data of a temporary defective sector using a sector where an off-track has occurred as a temporary defective sector. The reading module reads data from a target track. The cancellation processing module performs inter-track interference component cancellation processing with respect to the data read by the reading module using data written to a track adjacent to the target track, in which when a sector adjacent to a processing target sector in a track width direction is a temporary defective sector registered in the registering module, inter-track interference component cancellation processing is performed using data written to a substitute sector corresponding to the registered temporary defective sector.

    • An internal voltage adjusting circuit of a semiconductor memory device processes a period from activation to deactivation of a reset bar signal by dividing the period into a first period to a third period. In the first period, a peripheral circuit voltage is stabilized to a lowest value to suppress power consumption. In the second period in which a power source voltage is stabilized, the peripheral circuit voltage is set to a highest value to read out optimum internal voltage values from a fuse circuit in a stable manner. In the third period after reading out the optimum internal voltage values, the peripheral circuit voltage is returned to the lowest value to suppress the power consumption. When the reset bar signal is deactivated, the peripheral circuit voltage is set based on the optimum internal voltage values read out from the fuse circuit.
    • 半导体存储器件的内部电压调整电路通过将该周期划分为第一周期至第三周期来处理从复位条信号的激活到去激活的周期。 在第一期间,外围电路电压稳定在最低值以抑制功耗。 在电源电压稳定的第二时段中,将外围电路电压设定为最高值,以稳定的方式从熔丝电路读出最佳的内部电压值。 在读出最佳内部电压值的第三个周期中,外围电路电压返回到最低值以抑制功耗。 当复位条信号被去激活时,根据从熔丝回路读出的最佳内部电压值设定外围电路电压。
