    摘要: A memory cell array of a non-volatile semiconductor memory device includes unit strings grouped into first strings belonging to a first string group and second strings belonging to a second string group. Each unit string has a memory cells for storing data in a non-volatile state. Each first string is coupled between an associated bit line of a first bit line group and a first common source line whereas each second string is coupled between an associated bit line of a second bit line group and a second common source line. The bit lines and the common source lines are made of different conductive layers. In accordance with the invention, it is possible to achieve a less critical layout of sense amplifiers coupled to bit lines while easily performing a photolithography process as required in the manufacture of the memory device.

    摘要: A non-volatile memory device is disclosed in which a pair of two adjacent memory cell strings are commonly connected to one bit line and the memory cell strings are selectively driven to obtain a relatively wide pitch margin between two bit lines. The device has a conductive plate line which is located along each memory cell string or a pair of memory cell strings to drive memory cells thereof with a relatively low program voltage to a word line. The memory device comprises a plurality of memory cell strings which are arranged in parallel with one another and each of which extends in the same direction as a bit line 12, and a pair of two adjacent memory cell strings 11a and 11b are commonly connected to the bit line 12. The memory device also comprises a string selector for selecting either the first string 11a or the second string 11b in response to signals from string select lines SSL1 and SSL2, and a plurality of plate lines PLa or 21a and PLb or 21b which are respectively arranged on the first and second strings 11a and 11b. In the memory cell, if voltages having different levels are applied to the control gate of a memory cell of the string selected thus and the plate line, at least more than two coupling voltages are induced to a floating gate of a corresponding memory cell so that two bits of information can be stored in and read out of one memory cell. The memory device has a cell structure in which a pair of two adjacent memory cell strings are commonly connected to one bit line, so that margin width between two bit lines, i.e., a bit line pitch can be relatively widely obtained.
