Abstract
Designs of a sampling controller working with memory chips are described. The designs enable a memory chip to work in high frequency clocks, resulting in high data throughput rate. A data sampling device includes a memory chip and a sampling controller. The sampling controller includes an asynchronous data memory. A data writing port of the asynchronous data memory receives a clock signal and employs the clock signal as a writing clock to store the sampling data into an internal memory and activate a data reading port thereof to read and output the sampling data.
