In a semiconductor memory device, a memory cell is connected with a local sense amplifier and a global sense amplifier via a local bit line and a global bit line. The local sense amplifier is a single-ended sense amplifier including a single MOS transistor, which detects a potential of the local bit line which varies when reading and writing data with the memory cell. The threshold voltage of the MOS transistor is monitored so as to produce a high-level write voltage and a low-level write voltage, which are corrected and shifted based on the monitoring result so as to properly perform a reload operation on the memory cell by the global local sense amplifier. Thus, it is possible to cancel out temperature-dependent variations of the threshold voltage and shifting of the threshold voltage due to dispersions of manufacturing processes.

Real distribution order points with large quantities of mailing pieces are distributed between several virtual distribution order points with a minimum quantity of mailing pieces. The quantity of mailing pieces statistically determined for each real distribution order point of a defined distribution order are distributed between the virtual distribution order points, as regularly as possible, for the sorting passes preceding the final sorting pass. Then, the sorting passes preceding the final sorting pass are executed. The final sorting pass is thus executed, such that the mailing pieces of a distribution order are sorted into adjacent pigeon holes.

Radiographic apparatus and radiation detection signal processing method

Corrected X-ray detection signals are obtained by removing lag-behind parts through a recursive computation based on initial values determined from lag signal value (step T2). Thus, the lag-behind parts can be removed by taking into consideration lag signal values remaining at a starting point of the recursive computation. The lag signal values are dependent on the characteristic of an FPD (flat panel X-ray detector). By removing the lag-behind parts, with the lag signal values taken into consideration, the lag-behind parts are removed from X-ray detection signals with increased accuracy, without being influenced by the characteristic of the FPD.
