摘要:
For ODT (on-die termination) control within a memory module system, just one pin from the memory controller is used for sending command signals indicating an activated one of the memory devices. The activated memory device includes components that are turned on for generating the ODT control signal for controlling an ODT circuit of inactivated memory device(s). The components for generating an ODT control signal within the inactivated memory devices are turned off for minimized power consumption.

A delay locked loop (DLL) circuit for a synchronous semiconductor memory device which can control a delay time of a feedback loop within the DLL circuit according to the magnitude of an external load, and a method of generating information about a load connected to a data pin of a synchronous semiconductor memory device are provided. The DLL circuit includes a replica output driver delaying an internal clock signal by a first delay time to output a first internal clock signal, the first delay time is a delay time of the internal clock signal which is generated by an output driver when a first load of a first magnitude is connected to an output terminal of the output driver, and a transfer/delay circuit transferring the first delay internal clock signal to a phase detector as a second delay internal clock signal when the first load is connected to the output terminal, and outputting the second delay internal clock signal to the phase detector by delaying the first delay internal clock signal by a second delay time, the second delay time is a delay time of the internal clock signal which is generated by the output driver when a second load of a second magnitude, which is larger than the first magnitude, is connected to the output terminal.

The present invention relates to a multi-blade electric rotary razor which comprises a razor blade cartridge turned by a motor, and at least one pair of razor blade assemblies disposed at an equal-angle distance at the razor blade cartridge along a direction in which the razor blade cartridge rotates, at least one pair of razor blades (hereinafter referred to as first razor blades) being arranged in an overlapping manner at a predetermined distance at the razor blade assembly along a radius direction of the razor blade cartridge. The electric rotary razor of the present invention has a structure of a wet shaver where multiple razor blades are arranged, and uses the motor to turn the razor blade cartridge during shaving for user convenience and thorough shaving. The multi-blade razor blade assembly alleviates a dermal stimulation, minimizes a possibility of a scar, and does not require shaving cream, making shaving convenient and unhindered by time and space.
