-Address memory is a modular array of storage registers.  Each register within the array consists of a six-digit word capable of containing an address.   Each B2500 or B3500 system includes 24 words of address memory.  Six words are used by the processor to store the three addresses and other logical requirements of an instruction.   Two words contain real-time clock and control-time interval used by the software.   The remaining 16 words are used in pairs by the input/output channels for I/O operations.   A total of eight address memory extensions, each consisting of 12 words, can be added to a B3500 system.  Therefore, address memory is modular from 24 to 120 words in increments of 12 words.   The addition of input/output channels may require the addition of address memory extensions.+[[processor_state:address_memory|Address memory]] is a modular array of storage registers.  Each register within the array consists of a six-digit word capable of containing an address.   Each B2500 or B3500 system includes 24 words of address memory.  Six words are used by the processor to store the three addresses and other logical requirements of an instruction.   Two words contain real-time clock and control-time interval used by the software.   The remaining 16 words are used in pairs by the input/output channels for I/O operations.   A total of eight address memory extensions, each consisting of 12 words, can be added to a B3500 system.  Therefore, address memory is modular from 24 to 120 words in increments of 12 words.   The addition of input/output channels may require the addition of address memory extensions.
