Memory bank and its reference voltage generation circuit

Abstract

The invention provides a reference voltage generation circuit which is used for providing reference voltage for a memory bank. The memory bank comprises a data line pin and an address line pin. The reference voltage generation circuit comprises a first reference voltage generation circuit and a second reference voltage generation circuit. The first reference voltage generation circuit and the second reference voltage generation circuit are both directly electrically connected with the data line pin and the address line pin respectively so as to respectively provide reference voltage for the data line pin and the address line pin. The invention also provides the memory bank with the application of the reference voltage generation circuit. Reference voltage generated by the reference voltage generation circuit is stable and is convenient to maintain normal operation of the memory bank.

Description

technical field [0001] The invention relates to a reference voltage generation circuit, in particular to a reference voltage generation circuit applied to memory sticks. Background technique [0002] With the powerful functions of electronic products such as personal computers and servers, the capacity, computing speed and power consumption of memory sticks have been greatly improved. In actual use, the reference voltage (VREFDQ) of the data line on the memory stick and the reference voltage (VREFCA) of the address line must be kept stable to ensure the normal operation of the memory stick. However, in the existing design, the reference voltage of the data line and the reference voltage of the address line are both generated on the motherboard of the electronic product and transmitted to the memory stick through the transmission line. Due to the long transmission distance, it is easy to cause electrical signal distortion and affect The reference voltage of the data line and...

Problems solved by technology

However, in the existing design, the reference voltage of the data line and the reference voltage of the address line are both generated on the motherboard of the electronic product and transmitted to the memory stick through the transmission line. Due to the long transmission distance, it is easy to cause electrical signal distortion and affect The reference voltage of the data line and the reference voltage of the address line are stable

On the other hand, in order to reduce the interference of surrounding electronic components, the above two reference voltages are generally output directly by integrated circuits (Integrated Circuit, IC), but this increases the design cost of electronic products
