A digital-to-analog converter includes a first channel configured to output a first ramp voltage through an output node, and a first bias circuit configured to apply a bias voltage to the first channel. The first channel comprises a plurality of current cells connected to the first bias circuit, a plurality of selection circuits and a plurality of switches, and a first resistor connected to the output node. Each of the plurality of selection circuits of the first channel comprises a first selection circuit configured to connect a current of one of the plurality of current cells to the first resistor in accordance with a first digital input signal, and a second selection circuit configured to connect the current of the current cell to one of the plurality of switches corresponding to the current cell in accordance with a second digital input signal complementary to the first digital input signal.

Digital-to-analog signal converter and image sensor including the same

Disclosed is an electronic device comprising: a memory in which instructions are stored; and a processor electrically connected to the memory. The processor, when the instructions stored in the memory are executed: acquires a command for installation of a first application signed with a first key; checks information relating to the first key in a key storage of the electronic device; if the first key is determined to be valid, installs the first application; and if the first key is determined to have been revoked, controls to prohibit installation of the first application.

Method for signing key management by electronic device, and electronic device therefor

An electronic device using a division permission and an operating method thereof are disclosed herein. The electronic device includes a processor or a memory storing at least one instruction executable by the processor, and when the at least one instruction is executed by the processor, the processor receives a request for installing a first application on an electronic device, acquires a division permission information corresponding to a signature permission declared by the first application, applies the division permission information to a database, installs the first application. The division permission information may be used for the signature permission on a second application different from the first application.

Electronic device using division permission and operation method thereof

A semiconductor device includes: a memory test circuit that outputs a fourth signal based on a logic level of a second signal corresponding to a first signal output by a host and a logic level of a third signal; a memory device that becomes active or inactive based on a logic level of the fourth signal; and a test logic that outputs the third signal and performs a retention test on the memory device based on the logic level of the second signal.

Semiconductor device and retention test method

According to various embodiments, an electronic device may include: a touch-sensitive display; a processor operatively connected to the display; and a memory operatively connected to the processor, wherein the memory may store instructions that, when executed, cause the processor to: control the display to provide a right setup screen that enables a user to select data which an application is allowed to access among data stored in the memory, receive a read request for the data stored in the memory from the application, select data to be provided to the application among the data stored in the memory based on an access right policy established using the right setup screen, and provide the selected data to the application in response to the read request.

Electronic device for providing privacy services

In an example embodiment, a ramp generator includes a ramp circuit that receives a first ramp enable signal from a control circuit during a first ramp period, the first ramp period including a first reset period and a first sensing period, and the ramp circuit being configured to output a first ramp signal to a correlated double sampling circuit; an emphasis circuit that increases a voltage level of the first ramp signal during the first reset period, based on a first enable signal received from the control circuit; and a pre-emphasis circuit that further increases the voltage level of the first ramp signal during a first pre-emphasis period in the first reset period, based on a second enable signal received from the control circuit.

Ramp generator including emphasis circuit and pre-emphasis circuit, operation method thereof, and image sensor device including the ramp generator

An electronic device is disclosed that includes a memory storing a first application run based on a first sandbox environment and a processor connected with the memory. The memory stores instructions which, when executed, cause the processor to determine whether it is necessary to change a first user identifier (UID) for the first application in response to an application installation request requesting to update the first application to a second application, assign a second UID for the second application using a UID mapping resident program based on it being necessary to change the first UID, and construct a second sandbox environment for the second application to have the second UID and a resource included in the first sandbox environment.

Method and apparatus for managing application

Disclosed is an electronic device including: a communication interface comprising communication circuitry; a processor electrically connected to the communication interface; and a memory electrically connected to the processor, wherein the memory stores instructions which, when executed by the processor, cause the electronic device to: receive information on a status of at least one external device, information related to a location of the electronic device, and information related to a location of at least one external electronic device from a server through the communication interface; identify whether to output the status of the at least one external device based at least in part on the information related to the location of the electronic device and the information related to the location of the at least one external electronic device; and output the status of the at least one external device in response to identification of the output of the status of the at least one external device.
