  • Publication number: 20200118631
    Abstract: A method for operating a low-current EEPROM array is disclosed. The EEPROM array comprises bit line groups, word lines, common source lines, and sub-memory arrays. Each sub-memory array includes a first memory cell and a second memory cell. The first memory cell is connected with one bit line of a first bit line group, a first common source line, and a first word line. The second memory cell is connected with the other bit line of the first bit line group, the first common source line, and a second word line. The first and second memory cells are operation memory cells and symmetrically arranged at two sides of the first common source line. The method uses special biases to perform the bytes writing and erasing with low current, low voltage and low cost.

  • Publication number: 20200058523
    Abstract: A gas etching device includes an upper cover having a first gas exhausting channel that surrounds a first accommodation space. A lower cover has a second accommodation space where a wafer is located. The lower cover can connect with the upper cover. A gas jetting element is arranged in the first accommodation space to communicate with the upper cover. The gas jetting element receives etching gas from outside the upper cover and jets the etching gas in the first accommodation space and the second accommodation space to react with the wafer. The reacted etching gas is exhausted through the first gas exhausting channel. The first gas entering channel continues receives high-pressure gas from outside the upper cover and transmits the high-pressure gas to the second gas entering channel, so as to avoid leaking the etching gas.

  • Patent number: 10034323
    Abstract: A control method, suitable for a host device including a Bluetooth low energy communication circuit, includes following operations. A high priority list is obtained. The high priority list includes information about at least one first peripheral device. The BLE communication circuit is triggered to perform a first scan to search for any peripheral device around the host device. A first search result of the first scan is compared with the high priority list. In response to that the first search result covers all of the at least one first peripheral device in the high priority list, the BLE communication circuit is triggered to stop the first scan. The BLE communication circuit is triggered to communicate with the at least one first peripheral device found in the first scan.
