摘要： Various embodiments for implementing refresh mechanisms in dynamic semiconductor memories that allow simultaneous read/write and refresh operations. In one embodiment, the invention provides a synchronous multi-bank dynamic memory circuit that employs a flag to indicate a refresh mode of operation wherein refresh operation can occur in the same bank at the same time as normal access for read/write operation. In a specific embodiment, to resolve conflicts between addresses, an address comparator compares the address for normal access to the address for refresh operation. In case of a match between the two addresses, the invention cancels the refresh operation at that array and allows the normal access to proceed.
