Abstract:
The present disclosure relates to a technology for a sensor network, machine to machine (M2M) communication, machine type communication (MTC), and Internet of things (IoT). The present disclosure may be utilized for an intelligent service (smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, security and a safety-related service, etc.) on the basis of the technology. A method for providing a push-to-talk (PTT) service in a communication system, which is proposed by an embodiment of the present disclosure, comprises the steps of: generating a file format including information associated with time points at which multiple pieces of data should be reproduced; and reproducing the multiple pieces of data on the basis of the file format.
Abstract:
A split-gate type nonvolatile memory device includes a semiconductor substrate having a first conductivity type, a deep well having a second conductivity type in the semiconductor substrate, a pocket well having the first conductivity type in the deep well, a source line region having the second conductivity type in the pocket well, an erase gate on the source line region, and a first floating gate and a first control gate stacked sequentially on the pocket well on a side of the erase gate. The pocket well is electrically isolated from the substrate by the deep well, so that a negative voltage applied to the pocket well may not adversely affect operation of other devices formed on the substrate.
