    摘要: Provided are a semiconductor memory device and a method of programming the same. The semiconductor memory device includes a mode input value generating unit and a logic operating unit. The mode input value generating unit changes a connection state between input values of a current driving circuit so as to correspond to each of at least two operating modes, and defines a logic function of a magnetic memory cell connected to the current driving circuit in response to each operating mode. The logic operating unit performs a logic operation on the logic functions of at least two magnetic memory cells defined according to each of the operating modes and generates a result of logic operation.

    摘要: A spin transfer torque magnetic random access memory (STT-MRAM) and includes: a memory cell and a reference cell configured to operate as a reference when data stored in the memory cell is read. The memory cell includes: a first magnetic tunneling junction (MTJ) element and a first transistor connected to the first MTJ element. The reference cell includes: second and third MTJ elements connected in parallel; and second and third transistors that are connected to the second and third MTJ elements, respectively. The STT-MRAM further includes a control circuit having a write circuit configured to supply write currents having opposite directions to the second and third MTJ elements.
