Abstract
A combination precharge/activate command is utilized in order to make more efficient use of a command bus between a memory controller and a system memory. Upon receiving a precharge/activate command from the memory controller, the system memory makes a determination as to how to interpret the command depending on a page status. For an open page, the precharge/activate command is treated as a precharge command and then the system memory performs an activate with proper command timing using address and bank given during precharge/activate command. For a closed page, the precharge/activate command is treated as an activate command.
