摘要:
Provided are a phase-change memory device and method that maintains a resistance of a phase-change material in a set state within a constant resistance range; In the method, data is provided to a first phase-change memory cell and then it is first determined whether data stored in the first phase-change memory cell and the data provided to the first phase-change memory cell are identical. If the data stored in the first phase-change memory cell and the data provided to the first phase-change memory cell are not identical, a complementary write current is provided to the first phase-change memory cell and it is second determined whether the data stored in the first phase-change memory cell and the data provided to the first phase-change memory cell are identical; If the data stored in the first phase-change memory cell and the data provided to the first phase-change memory cell are identical, data is provided to a second phase-change memory cell;

摘要:
A semiconductor memory device includes a memory cell array and the memory cell array includes: a plurality of memory blocks and at least one setting unit. The at least one setting unit stores a location and a size of a boot data storage region within the plurality of memory blocks that stores boot data. The at least one setting units may include a register for setting usage of each memory block as a boot block. The semiconductor device may be a phase-change memory.
