System-on-chip including on-chip clock controller and mobile device having same

Abstract

The present invention provides a system-on-chip including an on-chip clock controller and a mobile device having the same. A system on chip (SoC) includes a logic circuit having a scan flip-flop and an on-chip clock controller. Scan flip flops are configured to store data using passive keeper. The on-chip clock controller is configured to receive a reference clock for driving the logic circuit, generate an internal clock at high-state intervals based on the reference clock, and provide the internal clock to the scan flip-flops.

Description

technical field [0001] Embodiments of the inventive concept relate to a system on chip (SoC), and more particularly, to an SoC including an on-chip clock controller for controlling the duty cycle of an internal clock to drive a scan flip-flop using a passive keeper and Mobile device with SoC. Background technique [0002] With increasing competition in the mobile device market, the requirements for mobile devices to have low price, low power consumption, and high performance are rapidly increasing. To meet these requirements, system-on-chip (SoC) design overhead needs to be reduced or eliminated. [0003] An example of typical design overhead is test cost. However, when the SoC is not tested, more costs are required for reliability verification of mass production. Therefore, testing should be considered when designing an SoC. Contents of the invention [0004] Embodiments of the inventive concept provide a system on chip (SoC) having low power consumption and high perf...
