    • An array of non-volatile memory cells is arranged in a plurality of rows and columns, wherein each memory cell has at least three terminals: a first terminal for the read out of the signal from the memory cell, a second terminal to which high voltage is supplied during certain operation, and a third terminal to which low voltage is supplied in all operations. The cells in the same column have a common bit line connected to the first terminal of memory cells in the same column. The array comprises a first and second sub arrays of memory cells arranged adjacent to one another in the same row. A first decoder is positioned to one side of the first sub array in the same row as the first sub array. A second decoder is positioned to another side of the second sub array in the same row as the second sub array. A first high voltage line is connected to the second decoder and to only the second terminal of the memory cells in the same row in the first sub array. A second high voltage line, different from the first high voltage line, is connected to the second decoder and to only the second terminal of the memory cells in the same row in the second sub array. A low voltage line is connected to the first decoder and to the thirds terminal of the memory cells in the same row of the first and second sub arrays.
    • 一组非易失性存储单元被布置成多个行和列,其中每个存储单元具有至少三个端子:用于从存储单元读出信号的第一端子,高电压的第二端子 在一定操作期间提供,并且在所有操作中提供低电压的第三端子。 同一列中的单元具有连接到同一列中的存储器单元的第一端的公共位线。 阵列包括在同一行中彼此相邻布置的存储单元的第一和第二子阵列。 第一解码器位于与第一子阵列相同的行中的第一子阵列的一侧。 第二解码器被定位在与第二子阵列相同的行中的第二子阵列的另一侧。 第一高压线路连接到第二解码器,并且仅连接到第一子阵列中的同一行中的存储器单元的第二端子。 与第一高压线不同的第二高压线路连接到第二解码器,并且仅连接到第二子阵列中同一行中的存储器单元的第二端子。 低电压线连接到第一解码器和第一和第二子阵列的同一行中的存储器单元的第三端子。
