Patent number: 8593470Abstract: A power adjustment circuit includes memory controller logic that is couplable to system memory or other memory if desired. The memory control logic is operative to provide a variable memory clock signal to the system memory and to place the system memory in a self refresh mode wherein the self refresh mode does not require a memory clock signal. Thereafter, the memory clock control logic adjusts the frequency of the memory clock signal to a lower (or higher) frequency clock signal, and in response to the frequency of the memory clock signal becoming stable, the memory clock control logic restores the memory to a normal mode using the lower adjusted frequency memory clock signal. As such, a dynamic memory clock switching mechanism is employed for quickly varying the frequency of memory modules for discrete graphics processors, graphics processors integrated on a chip, or any other processors such that the memory clock can be reduced to a lower frequency in real time to save power.Type: GrantFiled: February 24, 2005Date of Patent: November 26, 2013Assignee: ATI Technologies ULCInventors: John Bruno, Erwin Pang

Patent number: 8570067Abstract: An integrated circuit is capable of controlling a communication signal by using power ramp controlled communication buffer logic to generate an outgoing communication signal based on a detected voltage on a voltage source. The voltage source is necessary to supply power for power ramp controlled communication buffer logic. The voltage on the voltage source may be detected using power ramp sensor logic. The outgoing communication signal is based on a core logic output signal if the detected voltage is greater than or equal to a predetermined voltage level. If, the detected voltage is less than the predetermined voltage level, the outgoing communication signal is predetermined to be one of: a tristate outgoing communication signal, a logic one outgoing communication signal and a logic zero outgoing communication signal. Power ramp controlled communication buffer logic may also generate a core logic input signal based on an incoming communication signal in response to the detected voltage.Type: GrantFiled: May 15, 2007Date of Patent: October 29, 2013Assignees: ATI Technologies ULC, Advanced Micro Devices, Inc.Inventors: Oleg Drapkin, Grigori Temkine, Marcus Ng, Kevin Yikai Liang, Arvind Bomdica, Siji Menokki Kandiyil, Ming So, Samu Suryanarayana
