Arrangement for uniform utilisation of several addressable memory positions of an EEPROM

摘要

An arrangement for uniform utilisation of several addressable memory positions of an EEPROM in a telecommunication terminal is given. Digit sequences of number or charging information are written to the individual memory positions, and the number of memory positions is greater than the desired number of digit sequences to be stored simultaneously. The arrangement includes an address memory in the EEPROM, which contains the address of the currently used memory position, and gives it to an address control unit to address this memory position for writing and/or reading a digit sequence. An address memory control unit is provided, and puts the next address which is assigned to the next memory position into the address memory, if the address memory control unit, before a writing event, recognises a predefined criterion for moving forward in the digit sequences to be written and/or in the user control commands.
