Storing Data: To write data, a high voltage (around 15-20V) is applied to the control gate above the floating gate. This causes electrons from the transistor’s channel (the substrate) to “tunnel” through the thin oxide barrier via a quantum mechanical process called Fowler-Nordheim tunneling. The electrons get trapped in the floating gate, creating a negative charge. The presence and amount of this charge shift the cell’s threshold voltage—the voltage needed to turn the transistor on during a read operation.

Alison Taylor, a professor of business and society at NYU’s Stern School of Business said being deeply well-read is becoming something of a luxury good—rare, valuable, and impossible to fake.
这是一个“存量增量分步走、虚拟物理相结合”的算电协同方案。简单来说，对于数据企业的存量负荷，由于“物理直供”的改造成本较高，可以利用已建成的设施，通过市场交易的方式“虚拟直供”；而对于数据中心的增量负荷，则可以利用新建设施，“物理直供”给数据中心使用，配套的储能系统还能把用不完的电存下来。在夜晚、阴雨天等光伏不发电时段，系统再“回切”——让风电来填补光伏留下的缺口，进而实现24小时不间断的绿电覆盖。“通过物理直连和双边交易，既保障了数据中心的绿电需求，又解决了新能源项目的就地消纳难题。”靳良说。
Ранее Дональд Трамп дал в цифрах характеристику американо-израильской военной операции в Иране. По его словам, боевые действия идут на «15 из 10». «У нас все идет очень хорошо на военном фронте, это мягко сказано», — сказал американский лидер.
