<p>PURPOSE: To obtain a system and a method having large memory capacity to be infinitely extended without complicating a reference system by preparing one or more individual memory units and the small number of separated address lines. CONSTITUTION: Each module is included in a square expressed by a dotted line 2, external elements are common to various modules and each module is provided with a counter 4 for advancing its step through a memory by binary counting on an output address line 6. The counter 4 has a reset input 8 for executing reset in order to access the start end of a digital memory 10. The memory 10 is preferably constituted of an EPROM. Thereby even when many additional memory modules are added, only a start line, a stop line, a reset line, a high speed access line, and a clock control line are required. Consequently the much volume of the memory 10 can be accessed and the system can be highly flexibly and highly expansively applied to a digital audio storage system by a minimum control line.</p> |
