Polymer random access memory (PoRAM) is the next-generation of nonvolatile memory device which can overcome density and efficient problems of the flash memory. PoRAM has a diode cell switch to reduce the cell size without loss of the leakage current and cross-point resistor structure composed of an improved organic material (a conductive small-molecule organic layer embedded with Ni nanocrystals surrounded by a NiO tunneling barrier) with bi-stable electric switching characteristic between the top and bottom aluminum (Al) electrodes. In this paper, we propose that a sub-block configuration, RPE(read/program/erase) operation concepts, RPE driver system which supplies the high voltage for the each operation and a current sense amplifier suitable for PoRAM according to the control logic signal. The proposed sub-block is configured with the unit cell in the matrix structure that is composed of a row/column line, local row/column decoders, charge/discharge circuit, input/output (I/O) circuit, sense amplifiers and RPE driver with the control logic signal. The RPE driver system generates the operation voltages effectively which are applied the memory array, because the core circuit requires the stable high voltage exactly during the fast time. A memory array of a sub-block with the diode cell switch was fabricated for the 0.13um CMOS technology.
