摘要: The invention provides a dynamic random-access memory (DRAM) and an operation method thereof. The DRAM includes a memory cell array, a temperature sensor, and a refresh logic circuit. The temperature sensor senses a temperature of the DRAM. The refresh logic circuit enters a tRFC based on a refresh command issued by a memory controller to perform an automatic refresh operation on at least one memory cell row of the memory cell array. In a temperature-controlled refresh mode, the refresh logic circuit correspondingly adjusts a number of a plurality of tRAS periods in the tRFC according to a temperature sensing result of the temperature sensor. In a fine granularity refresh mode, the refresh logic circuit correspondingly adjusts the number of the tRAS periods in the tRFC according to a granularity specified by the memory controller.

摘要: A manufacturing method of a semiconductor device includes forming a bitline on a semiconductor structure comprising a conductive feature therein. A spacer is formed adjacent to a sidewall of the bitline, and the spacer has a dielectric contact in a range of about 2 to about 3. A sacrificial layer is formed over the semiconductor structure and covering the spacer. A portion of the sacrificial layer over the bitline is etched to form a first trench to expose a top surface of the bitline. A dielectric layer is formed in the first trench and over the bitline. After forming the dielectric layer, a remaining portion of the sacrificial layer is removed to form a second trench over the semiconductor structure and an outer sidewall of the first spacer is exposed. A contact is formed in the second trench and connected to the conductive feature of the semiconductor structure.
