Title:
TEMPERATURE COMPENSATION CIRCUIT AND METHOD FOR STORAGE AND OPERATION ARRAY OF NEURAL NETWORK
Document Type and Number:
WIPO Patent Application WO/2022/267912
Kind Code:
A1
Abstract:
Disclosed in the present invention are a temperature compensation circuit and method for a storage and operation array of a neural network. A reference voltage is provided for an ADC by means of a reference array that is sparsely inserted in a storage and operation array, such that an input voltage of the ADC has the same temperature coefficient as the reference voltage, and finally the ADC is used to perform analog-to-digital conversion, such that a digital output of the ADC is not affected by an external temperature, thereby guaranteeing the operation precision of a neural network. The reference array used in the temperature compensation circuit according to the present invention has the same structure as a storage and operation array, the insertion density of the reference array is related to a temperature field in which the storage and operation array is located, one reference array can be used to simultaneously provide the reference voltage of an ADC for a plurality of storage and operation arrays, thereby reducing, to the greatest extent, the increase in the area and power consumption caused by the insertion of a reference array. The temperature compensation method in the present invention is applicable to a 3D stacking technique in which a device array and an array peripheral circuit are placed in the same or different layers, and meets the requirements of developing storage and operation arrays in a large-scale direction.
