Abstract
An SDRAM access control section activates a row of an SDRAM when a request is made to access the row in the continuous access mode. The SDRAM access control section outputs a read command or a write command to the SDRAMwhen a request is made to access the SDRAM, without deactivating the accessed row, until a detection signal that detects the last column is asserted. The SDRAM access control section deactivates the accessed row when the detection signal is asserted.
