Abstract: A device includes a memory array, bit line pairs, word lines, a modulation circuit and a control signal generator. The memory array has bit cells arranged in rows and columns. Each bit line pair is connected to a respective column of bit cells. Each word line is connected to a respective row of bit cells. The modulation circuit is coupled with at least one bit line pair. The control signal generator is coupled with the modulation circuit. The control signal generator includes a tracking wiring with a tracking length positively correlated with a depth distance of the word lines. The control signal generator is configured to produce a control signal, switching to a first voltage level for a first time duration in reference with the tracking length, for controlling the modulation circuit. A method of controlling aforesaid device is also disclosed.

Abstract: A bio reader includes a casing defined therein a receiving space to receive therein a circuit board, a monitor electrically connected to the circuit board and a strip connector electrically connected to the circuit board for receiving therein a strip. The strip connector has a base mounted in the casing, a push movably connected to the base and having a ridge formed thereon for abutment of a strip on top of the push and an extension extending into the base and a retracting finger securely connected to the push and adapted to be slidably mounted on a side of the casing such that movement of the retracting finger is able to drive the push to move such that the strip on top of the push is also moved.
