Abstract

A clock skew elimination method for 3D stacked memory, a clock skew elimination circuit for 3D stacked memory, and a 3D stacked memory. The clock skew elimination method includes: according to the original signal phase of the write data strobe pin and the phases of all data pins The raw signal phase generates the preset digital clock phase such that the preset digital clock phase lags the raw signal phase of the data strobe pin and the raw signal phase of each data pin; compares the raw signal phase of the data pin with the preset The digital clock phases are compared, and the original signal phase of each data pin is delayed to ensure that the signal phase of each data pin is consistent with the preset digital clock phase; Delay control is performed on the data pins to eliminate pin skew and improve data transmission reliability of the 3D stacked memory.

Description

technical field [0001] The present application belongs to the technical field of electronic circuits, and in particular relates to a clock skew elimination method for a 3D stacked memory, a clock skew elimination circuit for a 3D stacked memory, and a 3D stacked memory. Background technique [0002] With the rapid development of electronic technology, large-scale integrated circuits have gradually been widely used in the daily industrial production process. Since electronic equipment will generate a large amount of data input and output during work, in order to ensure the stability and safety of electronic equipment Therefore, it is necessary to store and retain the data transmitted by the electronic equipment in real time, so as to control the electronic equipment in real time according to the stored data; therefore, the storage security and storage capacity of the data will play an important role in the circuit control process of the electronic equipment. Extremely importa...
