Title:
DATA PROCESSING CIRCUIT AND METHOD, TRANSMITTING CIRCUIT, AND SEMICONDUCTOR MEMORY
Document Type and Number:
WIPO Patent Application WO/2023/226086
Kind Code:
A1
Abstract:
Embodiments of present disclosure provide a data processing circuit and method, a transmitting circuit, and a semiconductor memory. The data processing circuit comprises a preprocessing module and a driving module. The preprocessing module is configured to: receive an initial data signal; and generate, according to the initial data signal, a data signal to be processed and an auxiliary data signal, wherein the initial data signal is a parallel data signal, the data signal to be processed and the auxiliary data signal are both serial data signals, and the auxiliary data signal and the data signal to be processed have opposite phases and are delayed by a preset clock period. The driving module is connected to the preprocessing module and is configured to: perform adjustment processing on an initial calibration code according to a preset scene to obtain a target calibration code; perform resistance value adjustment on driving resistance of the driving module according to the target calibration code; and perform driving capability adjustment on the data signal to be processed according to the auxiliary data signal and the adjusted driving resistance to generate a target data signal.
