摘要：A memory and a method for communicating therewith are implemented havinga unidirectional write bus for writing to memory cells within a plurality of memory cellgroups. Local bitlines associated with each of the memory cell groups communicate writedata to the associated memory cell. Global bitlines coupled to all of the memory cellsare decoupled from the local bitlines during a write operation. Following a writeoperation the local bitlines are restored by a precharge operation during which theglobal and local bitlines are also decoupled.
