A particle counting method is provided whereby a liquid sample is radiated by a laser light, scattered light produced by causing the laser light to hit a particle in the liquid sample is detected by a photoelectric conversion element, and a sample value which is the output of the photoelectric conversion element is sequentially compared to a threshold preset for each particle size range, thereby counting the number of particles for each particle size range, the method comprising: a timer start-up step for starting a timer of a predetermined time when the sample value becomes smaller than a threshold of a minimum particle size for the first time and for sequentially holding the maximum value of the sample value; and a timer extension step for restarting the timer to sequentially hold the maximum value of the sample value when the sample value at the time-out of the timer start-up step is larger than the threshold of the minimum particle size.

A nonvolatile memory apparatus which need not compare an access address with a faulty address every time for rescuing from any fault is to be provided. The apparatus has memory arrays, data registers for inputting and outputting data to and from the memory arrays, and control circuits. The control circuits, after transferring a plurality of sets of data from the memory arrays to the data registers in response to an instruction to read data, take out rescuing data out of the plurality of sets of data transferred to the data registers, and perform processing to replace with the taken-out rescuing data corresponding faulty addresses on the data register to enable the data on the data register to be supplied to the outside. When any faulty data in the read data are to be replaced with rescuing data on any data register to which data have been transferred from any memory array, read access addresses need not be checked whether or not they are faulty every time an access address is supplied from outside.
