Abstract: Disclosed herein are related to a memory system including unit storage circuits. In one aspect, each of the unit storage circuits abuts an adjacent one of the unit storage circuits. In one aspect, each of the unit storage circuits includes a first group of memory cells, a second group of memory cells, a first sub-word line driver to apply a first control signal to the first group of memory cells through a first sub-word line extending along a direction, and a second sub-word line driver to apply a second control signal to the second group of memory cells through a second sub-word line extending along the direction. In one aspect, the memory system includes a common word line driver abutting one of the unit storage circuits and configured to apply a common control signal to the unit storage circuits through a word line extending along the direction.

Abstract: A device is disclosed and includes an input stage circuit, a switching circuit, and a first latch circuit. The input stage circuit generates a first input signal having a first voltage and a second input signal based on a third input signal. The switching circuit operates in response to a first control signal, and adjusts a voltage level of a first data line according to the first input signal and a voltage level of a second data line according to the second input signal. The first latch circuit is coupled to the switching circuit by the first data line and the second data line. The first latch circuit latches a data in response to the first control signal and a second control signal, and adjusts the voltage level of the first data line based on a second voltage different from the first voltage.

Abstract: A high/low voltage tolerant interface circuit and a crystal oscillator circuit using the same are provided herein. The interface circuit includes a first transistor, a bulk-voltage generator module and an bias module. The first transistor includes a gate, a first source/drain, a bulk coupled to the first source/drain of the first transistor and a second source/drain coupled to an input node. The bulk-voltage generator module is, used to determine whether a first voltage or a predetermined voltage is being provided to the bulk of the first transistor according to the voltage of the input node. The bias module is coupled to the gate of the first transistor. The bias module is used to provide an bias voltage to the gate of the first transistor and makes the first transistor conduct in order to control the voltage of the second source/drain voltage of the first transistor.
