Filed:

Aug 7, 1998

Appl. No.:

9/130664

Inventors:

Terry Jeng - Saratoga CA
Chuan-Yu Wu - Keelung, TW
Jason Hou - Fremont CA

Assignee:

Powerchip Semiconductor Corp. - Hsin-Chu

International Classification:

G11C 800
G11C 700

US Classification:

36523003

Abstract:

A synchronous dynamic RAM capable of segmentally precharging each memory bank. In this SDRAM, each memory bank is divided into multiple memory blocks. Each of these memory blocks internally has its own row access circuitry, but performs independent precharging operation. Access to the memory bank can be cooperative externally, and precharge operation can be separately applied to these memory blocks while allowing utilization of row cache that is available on other blocks. The SDRAM further includes a control device for generating a dedicated precharge signal to each memory block according to a precharge signal for each memory bank. Each dedicated precharge signal independently precharges the corresponding memory block regardless of the access operations executed by other memory blocks. The dedicated precharge signal and a succeeding activate signal for activating a different memory block are overlapped in timing so that the precharge sequence is implanted in the succeeding activate signal and the data access time is shortened.

15/836504

Inventors:

- Campbell CA, US
Manolis Terrovitis - Athens, GR
Masoud Zargari - Irvine CA, US
Jason Chih-way Hou - San Jose CA, US
Teresa Huai-Ying Meng - San Francisco CA, US

International Classification:

H02J 50/20
H04B 5/00

Abstract:

Method and apparatus for wirelessly transmitting and receiving power between devices are provided. A first device may convert power into RF energy and transmit the RF energy to a second device. In some implementations, the first device may steer the RF energy using beamforming techniques to the second device. The second device may receive and convert the RF energy into power for the second device. In some implementations, the second device may be powered solely or in part by power transmitted by the first device. In some implementations, the first device may include two or more RF energy harvesters and a power combiner. The power combiner may combine power from the two or more RF energy harvesters to power the second device and/or charge a battery.

Appl. No.:

13/766700

Inventors:

- San Diego CA, US
Jason Hou - Millbrae CA, US
Yoseph Malkin - Palo Alto CA, US

Assignee:

QUALCOMM Incorporated - San Diego CA

International Classification:

H04W 72/08

US Classification:

370329

Abstract:

A wireless access point (AP) stores a region code that identifies a country/region in which the wireless AP is designed to operate. This region code can be provided by the wireless AP vendor, or in response to information provided by the wireless AP user or a GPS receiver. In response to the region code, the wireless AP identifies one or more WiFi channels that are subject to interference within the region due to the non-WiFi wireless communication channels that are approved for use within the region. The wireless AP then selects a WiFi channel for wireless communication, wherein the wireless AP avoids selecting the WiFi channels identified as being subject to interference within the region.
