Abstract: In one aspect a method of storing data in an integrated circuit may include identifying a group of storage sites from a plurality of storage sites; selecting a plurality of storage levels, each storage level being assignable to a storage site in the group of storage sites; and assigning a unique storage level to each of the storage sites in the group of storage sites, each unique storage level assigned from the plurality of storage levels.

Abstract: A device for generating memory-internal command signals from a memory operation command includes a command input for receiving a memory operation command for performing a memory operation in a memory system, a clock signal input for receiving an external clock signal, and an output for applying the memory-internal command signal to a command signal line of the memory system. In the device, the memory-internal command signal is generated at a time which depends on the memory-internal command signal and which is selectively settable and synchronous with a rising or synchronous with a falling edge of the external clock signal.

Abstract: A device for generating memory-internal command signals from a memory operation command is provided comprising a command input for receiving a memory operation command for performing a memory operation in a memory system, a clock signal input for receiving an external clock signal and an output for applying the memory-internal command signal to a command signal line of the memory system. The device further includes a command signal generating means which is implemented in order to generate the memory-internal command signal using the memory operation command at a time which depends on the memory-internal command signal and which is selectively settable synchronous with a rising or synchronous with a falling edge of the external clock signal.
