Abstract: Embodiments of the present disclosure relate to an electrostatic protection structure and an electrostatic protection circuit. The electrostatic protection structure includes: a SCR structure and a trigger structure; the SCR structure includes: a well region of a second conductivity type and a first well of a first conductivity type region, a first-doped region of the first conductivity type, and a first-doped region of the second conductivity type; the trigger structure includes: a first-doped region of the second conductivity type, a second well region of the first conductivity type, a second-doped region of two conductivity types, a third-doped region of the second conductivity type, a fourth-doped region of the second conductivity type, and a first gate electrode.

Abstract: A discharge unit is connected to a power pad, a ground pad, and an I/O pad, and can discharge an electrostatic charge when an electrostatic pulse appears on any of the power pad, the ground pad, and the I/O pad. The discharge unit includes a first discharge unit and a second discharge unit, the first discharge unit is connected to the second discharge unit, the power pad, and the I/O pad, and the second discharge unit is connected to the ground pad and the I/O pad. The first discharge unit and/or the second discharge unit can discharge electrostatic charges on different pads, respectively.

Abstract: A method for acquiring user configuration information is provided. The method includes the following. A configuration file is stored as a server configuration file of a current service card in response to receiving the configuration file from a communications server, or configuration information is stored as a user configuration file of the current service card in response to the configuration information being set based on the configuration file, where at least one of the server configuration file of the current service card and the user configuration file of the current service card exists. When the current service card of a terminal is replaced with a replacement service card, prestored user configuration files is searched to find a user configuration file corresponding to the replacement service card, and user configuration information is acquired to perform a communications service according to the user configuration file corresponding to the replacement service card.

Abstract: The present disclosure provides a method and a terminal. The method includes the follows. When a communications server delivers a configuration file, or when a user performs setting based on the configuration file delivered by the communications server, the configuration file delivered by the communications server is stored as a server configuration file of a current service card, or configuration information set by the user based on the configuration file is stored as a user configuration file of the current service card. When the current service card of the terminal is replaced, the user configuration file of the current service card is searched to find a user configuration file corresponding to a replacement service card, and user configuration information is acquired according to the user configuration file corresponding to the replacement service card.
