摘要
An apparatus and a method for avoiding bank conflicts are provided to prevent performance of a processor from being lowered due to bank conflicts. Writing/reading units access to one bank according to an access command. A scheduling unit changes a performing time point of the first command among access commands for indicating access in the same bank into a previous time point to change the first command into the second command in order to enable the access commands not to indicate access in the same bank. A switching unit(190) enables one of the writing/reading units to receive read data at the performing time point of the first command from one bank according to the second command in consideration of a preoccupying table. The scheduling unit comprises a table storage unit(160), a bank conflict estimator(180) and a table updating unit(170). The table storage unit stores the preoccupying table showing access commands.
