Read Strobe Gating Mechanism

摘要

A memory controller that extends the window when reading data from the memory device to compensate for fluctuations in a read strobe delay. The memory controller includes a communication port that receives a timing reference signal for reading data from a memory device. A control circuit generates a gating signal indicative of a read window. A gating adjustment circuit generates an adjusted gating signal indicative of an adjusted read window based on the gating signal and the timing reference signal. A gating circuit generates a first gated timing reference signal for reading data by gating a delayed version of the timing reference signal with the adjusted gating signal.
