Abstract
A method and system for maximizing DRAM memory bandwidth is provided. The system includes a plurality of buffers to store a plurality of data units, a selector coupled to the buffers to select the buffer to which a data unit is to be stored, and logic coupled to the buffers to schedule an access of one of a corresponding number of memory banks based on the buffer in which the data unit is stored. The system receives a data unit, computes an index based on at least a portion of the data unit, selects a buffer in which to store the data unit based on the index, stores the data unit in the selected buffer, schedules a memory bank access based on the index, reads the data unit from the selected buffer, and accesses the memory bank.
