ABSTRACT:
A mixed-mode semiconductor memory includes a memory bank array, an analog/digital converter, a digital/analog converter, a plurality of digital buses and a control unit. The memory bank array includes a plurality of memory banks that are each composed of a plurality of pieces of single port memory. The analog/digital converter converts an input analog signal into digital information to store data corresponding to the input analog signal in the memory of the memory bank. The digital/analog converter converts a designated memory address of the memory bank into an analog signal to output the memory address in analog signal output form. The plurality of digital buses transmits the address and the digital information. The control unit sets 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. 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.
