Abstract
A dynamic random access memory employs either or both of a normal row copy operation or a fast row copy operation to copy selected data from a first row of memory to a second row of memory, without transferring the data to an intermediary processor such as a central processing unit or a memory controller. Both operations depend on a concurrent electrical activation of two separate wordlines within a bank of a DRAM. For the fast row copy operation, the two separate wordlines are part of a shared section of a DRAM bank, having shared bitlines. Bit values are copied directly in parallel via common bitlines. For the normal row copy operation, the two separate wordlines are part of a common bank but not a shared section. Bit values are copied in serial via a general input/output bus within the bank.
