    • 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
    • 集成电路存储器件具有以多个阵列排列的多个存储单元。 每个阵列具有多个行,多个列线以及连接到每个阵列中的存储器单元的多条行线。 阵列中的存储单元可由列线和行行寻址。 列地址解码器接收列地址信号并且响应地选择每个阵列的一个或多个列线。 行地址解码器接收行地址信号并且响应地选择每个阵列的行线。 存储器件还具有多个(k)个读出放大器,其中一个读出放大器与每个阵列相关联,可连接到阵列的一个或多个列线,并接收从寻址的存储器单元提供的信号。 存储器件还具有寄存器; 和控制电路。 控制电路接收读取命令,并且时钟信号,并且响应于读取命令,激活多个(k)个读出放大器(k)中的第一个(j)一段足以感测信号的时间段 在与多个(j)个读出放大器中的每一个相关联的连接列线上。 控制电路将信号锁存到寄存器中; 并且去激活所述第一多个(j)读出放大器; 并响应于时钟信号串行输出来自寄存器的信号。
