Semiconductor device including an arbiter cell

摘要

A semiconductor device is implemented with a technology for removing a command bubbling generated when performing a rank-to-rank switching on chips that are stacked and interconnected through a through silicon via (TSV). The semiconductor device includes a first memory, a second memory stacked over the first memory to input/output data through a TSV, and an arbiter configured to adjust first data received from the first memory and second data received from the second memory through the TSV and provide the adjusted data to an input/output (I/O) pad.

1. A semiconductor device comprising:
a first chip; a second chip stacked over the first chip, the first and second chips inputting or outputting data through a through silicon via (TSV); and an arbiter configured to adjust an output duration of first data read out of the first chip and an output duration of second data read out of the second chip, and provide output-duration adjusted data to an input/output (I/O) pad of the semiconductor device.
