Abstract:
A method and system for a DRAM having a first bank that includes a first sub-array (SA) and a second SA. The first SA includes a first storage unit coupled to a first row-buffer in a first sub-channel (FSC) and a second storage unit in a second sub-channel (SSC). The second SA includes a third storage unit and a fourth storage unit coupled to a second row-buffer. The first SA is associated with a first row address (RA) and the FSC is associated with a first column address (CA) stored in the FSC. The second SA is associated with a second RA and the SSC is associated with a second CA stored in the SSC. The first and second CAs are used to select portions of data from the first and second row-buffers, respectively, for output to a data bus.
