Abstract:
1. Mixed-mode semiconductor memory, comprising: a memory bank array comprising a plurality of memory banks that each comprise a plurality of pieces of single port memory; an analog/digital converter for converting an input analog signal into digital information to store data corresponding to the input analog signal in memory of the memory bank; a digital/analog converter for converting digital information stored in a designated memory address of the memory bank into an analog signal to output the digital information in analog signal output form; a plurality of digital buses for transmitting the address and the digital information; a control unit for setting the analog/digital converter and the digital/analog converter to store and output the digital information and the analog information and supplying an address signal to the memory bank; and a two-dimensional crossbar switch for setting up connections so that the plurality of digital buses can simultaneously access an identical memory bank or different memory banks of the memory bank array wherein the mixed-mode semiconductor memory can store analog and digital information at a same address and output stored information in analog or digital form, as desired.
