Title:
METHOD AND APPARATUS FOR ADJUSTING PHASE OF BIDIRECTIONAL DATA STROBE (DQS) SIGNAL
Document Type and Number:
WIPO Patent Application WO/2023/123796
Kind Code:
A1
Abstract:
The present application discloses a method for adjusting the phase of a bidirectional data strobe (DQS) signal, which is applied to the field of field-programmable gate arrays and is used for solving the problem of temperature drift of DQS signals in double data rate synchronous dynamic random access memories. The method provided by the present application comprises: receiving a phase adjustment instruction, and adjusting the phase of a DQS signal according to a preset first adjustment rule; receiving a signal sampling instruction to sample the DQS signal, and returning a sampling result of the DQS signal; determining whether the sampling result is correct, and storing the determining result; and cyclically executing the step of receiving a phase modulation instruction to the step of storing the determined sampling result, until the number of cyclic executions reaches a preset number; and adjusting the phase of the DQS signal according to the determining results corresponding to the number of cyclic executions and according to a preset second adjustment rule.
