    • A memory system includes a master device, such as a graphics controller or processor, and an integrated circuit memory device operable in a dual column addressing mode. The integrated circuit memory device includes an interface and column decoder to access a row of storage cells or a page in a memory bank. During a first mode of operation, a first row of storage cells in a first memory bank is accessible in response to a first column address. During a second mode of operation, a first plurality of storage cells in the first row of storage cells is accessible in response to a second column address during a column cycle time interval. A second plurality of storage cells in the first row of storage cells is accessible in response to a third column address during the column cycle time interval. The first and second pluralities of storage cells are concurrently accessible from the interface.

    • In a memory device, either a first portion or a second, smaller portion of data retrieved from a storage array is loaded into a data buffer in accordance with a prefetch mode selection and then output from the memory device via a signaling interface. A value that indicates a minimum number of cycles of a clock signal that are to transpire between successive accesses to any one of the storage resources may be received and stored within a configuration circuit of the memory device. If the value indicates a number of clock cycles, N, that is less than a threshold number, the memory device may transfer data associated with a first address between the signaling interface and the data buffer during each of N cycles of the clock signal. If N is greater than or equal to the threshold number, the memory device may transfer the data associated with the first address between the signaling interface and the storage buffer during each of X cycles of the clock signal, and then transfer data associated with the second address between the signaling interface and the storage buffer during each of X cycles of the clock signal, where X is an integer value less than N.
    • 在存储器件中,根据预取模式选择将从存储阵列检索的数据的第一部分或第二较小部分的数据加载到数据缓冲器中,然后经由信令接口从存储器件输出。 指示在对任何一个存储资源的连续访问之间发生的时钟信号的最小周期数的值可以被接收并存储在存储器件的配置电路中。 如果该值指示小于阈值数目的时钟周期数N,则存储器件可以在时钟信号的N个周期的每个周期期间传送与信令接口和数据缓冲器之间的第一地址相关联的数据。 如果N大于或等于阈值数,则在时钟信号的X个周期的每个周期期间,存储器件可以传送与信号接口和存储缓冲器之间的第一地址相关联的数据,然后传送与第二个 在时钟信号的X个周期的每个周期期间,信令接口和存储缓冲器之间的地址,其中X是小于N的整数值。
