    摘要: A phase change memory device and a write method thereof allow writing of both volatile and non-volatile data on the phase change memory device. The phase change memory device may be written by setting a write mode as one of a volatile write mode and a non-volatile write mode, and writing data as volatile or non-volatile by applying a write pulse corresponding to the write mode, wherein, when power is not supplied to the phase change memory device, the non-volatile data is retained and the volatile data is not retained.

    摘要: A number of read cycles applied to a selected memory location of a memory device, such as a variable-resistance memory device, is monitored. Write data to be written to the selected memory location is received. Selective pre-write verifying and writing of the received write data to the selected memory location occurs based on the monitored number of read cycles. Selectively pre-write verifying and writing of the received write data may include, for example, writing received write data to the selected memory cell region without pre-write verification responsive to the monitored number of read cycles being greater than a predetermined number of read cycles.

    摘要: A resistive memory device and a sensing margin trimming method are provided. The resistive memory device includes a memory cell array and a trimming circuit. The memory cell array has a plurality of resistive memory cells. The trimming circuit generates a trimming signal according to a characteristic distribution shift value of the resistive memory cells. With the inventive concept, although a characteristic distribution of memory cells is varied, an erroneous read operation is minimized or reduced by securing a sensing margin stably. Accordingly, a fabrication yield of the resistive memory device is bettered.
