Abstract
A control circuit receives the mode signals supplied from a mode register and a read enable signal READ supplied from a control logic circuit, which activates enable signals ENto ENbased on the mode signals and read enable signal. For example, the read enable signal READ is activated when a read command is issued from the controller. One mode signal can indicate an operation mode in which a multi-purpose register is used, and another mode signal can indicate an operation mode in which the data bus inversion function is used. When a data masking operation is disabled and an error check operation is enabled, the mode register activates a protection signal SEL. When the data masking operation is enabled or the error check operation is disabled, the protection signal SEL is deactivated. The operation of a deserializer is controlled by clock signals and the protection signal SEL.
