  • Publication number: 20240111433
    Abstract: In some embodiments, a memory system includes a memory device and a host configured to transmit, to the memory device, a command and address (C/A) signal and a clock signal, and to transmit or receive data signals to or from the memory device. Each command that is configured to access the memory device is associated with an access timing parameter. The memory device includes an access parameter timer configured to measure an actual timing value of the access timing parameter, a spec register configured to provide a spec timing value defining an effective timing of the access timing parameter, a comparison circuit configured to compare the actual timing value and the spec timing value, and a mode register configured to store an access timing violation flag that is read by the host when the actual timing value deviates from the spec timing value by exceeding a predetermined range.

  • Patent number: 7294546
    Abstract: A capacitor includes an upper electrode formed by physical vapor deposition and chemical vapor deposition. The upper electrode of the capacitor may include a first upper electrode formed by chemical vapor deposition and a second upper electrode formed by physical vapor deposition. Alternatively, the upper electrode may include a first upper electrode formed by physical vapor deposition and a second upper electrode formed by chemical vapor deposition. The upper electrode of the capacitor is formed through two steps using chemical vapor deposition and physical vapor deposition. Therefore, the upper electrode can be thick and rapidly formed, whereby electrical characteristics of the upper electrode are not deteriorated.
