Document Type and Number:

Japanese Patent JPH0779000

Kind Code:

B2

Abstract:

A counter has an electrically erasable and programmable read-only memory (EEPROM), a write circuit, and a read circuit. The EEPROM, which can be rewritten at least V times, is divided into count areas MO, . . . , MN each capable of storing count values from zero to V, and a number area for storing a number K from zero to N identifying the count area currently in use. The write circuit uses the count areas MO, . . . , MN in succession to store counts as high as NxV. The read circuit obtains the current count value by reading K from the number area, reading the contents C of the Kth count area MK, and calculating C+(VxK).
