    摘要： A ROM device includes a plurality of memory cells each storing one of three states, a cell voltage generating circuit for providing a cell voltage corresponding to the state stored in a selected one of the memory cells, and a reference cell for providing a reference voltage which is substantially the same as the cell voltage provided by a memory cell storing an intermediate state of the three states. The ROM also includes a comparator circuit for generating a logical output signal based on the result of a comparison between the cell voltage and the reference voltage.

    摘要： A plural-bit-per-cell read-only memory constituted by a memory cell array (1), reference cell array (2A, 2B, 2C), and related circuits. In the memory cell array (1), a low resistance ground line (17) crossing the diffusion layer in parallel with the bit lines (15) is arranged for each predetermined length of the diffusion layer, which is used as a common grounding route to the low resistance ground line (17). The reference cell array (2A) includes a plurality of reference cells (211, 212, . . . 21n), and the arrangement of the reference cells (211, 212, . . . 21n) corresponds to the arrangement of the plural-bit memory cells (14) within the predetermined length of the diffusion layer in the memory cells array (1). The transconductance of the reference cells is predetermined in correspondence with the reference voltage values (REF1, REF2, REF3). A column address signal which selects a plural-bit memory cell (14) also selects one of the reference cells (211, 212, . . . 21n) which corresponds to the plural-bit memory cell (14) selected by the column address signal. Thus, in generation of reference voltages (REF1, REF2, REF3), the reference voltage value is corrected taking into consideration the influence of resistance of the diffusion layer according to the location of the plural-bit memory cell (14) selected by the column address signal.

    摘要： A flip-flop type sense amplifier for a semiconductor memory device is disclosed, the sense amplifier comprising a pair of CMOS inverters cross-coupled with each other to form a CMOS flip-flop circuit having a pair of buffer circuits, for receiving the read-out voltage signals from multi-level memory cells and a predetermined reference voltage, respectively, and a pair of switching circuits for inverting a power source voltage across the flip-flop circuit through common sources of the flip-flop circuit, in response to the transition between a stand-by sequence and a latching operating. The common source of the p-channel transistors of the CMOS flip-flop circuit is connected to a negative potential source, and the common source of the n-channel transistors is connected to a positive potential source during a stand-by sequence, and vice versa, during a latching operation. This unique potential supply method enhances operational speed of the sense amplifier. In a multi-level memory device, a plurality of the sense amplifiers are connected in parallel for the discrimination of the read-out signals changing in a range of a few volts.
