A semiconductor device is provided. The semiconductor device comprises a first memory unit including a first memory area, and a first logic area electrically connected to the first memory area, the first logic area including a cache memory and an interface port. The first memory unit executes a data transmission and reception operation with a memory unit adjacent to the first memory unit via the first interface port and the cache memory.

Semiconductor device

A quadrature signal phase controller includes a first phase shifter and a second phase shifter. The first phase shifter generates phase shifted first in-phase differential output signals and phase shifted first quadrature-phase differential output signals. The second phase shifter generates phase shifted second in-phase differential output signals and phase shifted second quadrature-phase differential output signals. Each of the first and second phase shifters increases or decreases the phase difference between the first in-phase differential output signals and the second quadrature-phase differential output signals, and the phase difference between the second in-phase differential output signals and the first quadrature-phase differential output signals, in response to a change in a level of the first control signal and a change in a level of the second control signal.
