Abstract

Data transfers involving accesses of multiple banks of a DRAM having a shared sense amplifier architecture can be performed while also avoiding bank conflicts and associated data bus latency. Groups of DRAM banks which can be sequentially accessed during a given data transfer without conflicting with one another are identified and utilized for data transfers. Each data transfer sequentially accesses the banks of one of the groups. The sequence in which the banks of a given group will be accessed during a data transfer can advantageously be reordered in order to prevent conflicts with banks that have been or will be accessed during prior or subsequent data transfers. In this manner, consecutive data transfers, each involving accesses to multiple banks of a DRAM having a shared sense amplifier architecture, can be performed without any data bus latency between or within the transfers.
