摘要： An integrated circuit memory device has a plurality of memory cells arranged in a plurality of arrays. Each array has a plurality of rows, and a plurality of column lines, and a plurality of row lines connecting to the memory cells in each array. The memory cell in an array is addressable by a column line and a row line. A column address decoder receives a column address signal and selects one or more column lines of each array in response. A row address decoder receives a row address signal and selects a row line of each array in response. The memory device also has a plurality (k) of sense amplifiers, with one sense amplifier associated with each array, connectable to one or more column lines of the array and receives a signal therefrom supplied from an addressed memory cell. The memory device further has a register; and a control circuit. The control circuit receives a read command, and a clock signal, and in response to the read command activates a first plurality (j) of the plurality (k) of sense amplifiers (j

摘要： An integrated circuit memory device has an array of memory cells arranged in a plurality of rows and columns and a plurality of row lines and a plurality of column lines. Cells arranged in the same row are connected by a common row line, and cells arranged in the same column are connected by a common column line. Each cell in the array is addressed by an address signal which has a plurality of bits. A sense amplifier circuit is connectable to one or more of the plurality of column lines of the array. An address input terminal receives in series the plurality of bits of the address signal. Each of the column lines is connectable to a pre-charge voltage, in response to a read command. A decoder circuit receives the address signal and decodes the address signal as each of the plurality of bits is received and disconnects certain of the column lines to the pre-charge voltage in response to the decoding, and activates the sense amplifier circuit after all of the plurality of bits of the address signal are received.
