ABSTRACT:
A serial in random out memory circuit has a number of memory cells integrated with write control circuitry for writing a sequence of data inputs to sequential locations in the memory cells. Read control circuitry is integrated to receive address signals from an external device and provide a random access read output from the memory cells, mapped into an address range of the external device. Compared to circuits using discrete components and conventional RAM chips, the integrated SIRO can enable some of the circuitry or external software to be dispensed with and so reduce costs or increase performance. The memory cells can be arranged in a number of blocks, selectable one at a time for mapping to the external device address range.
