CIRCUITS, DEVICES, SYSTEMS, AND METHODS OF OPERATION FOR CAPTURING DATA SIGNALS |
摘要 |
Embodiments of the invention describe driving data onto a bus. The embodiments include a data driver circuit having a data capture circuit coupled to the bus. The data capture circuit receives data relative to a write strobe signal and captures a first digit of the data responsive to a first edge of the write strobe signal and at least a second digit responsive to a second edge of the write strobe signal. The data driver circuit includes a feedback capture circuit that captures each digit in substantially the same manner as the data capture circuit, and generates a latch control signal indicative of when each digit is latched. The latch control signal is provided to a write control circuit that determines which digit was latched first relative to a timing, and generates a select control signal to drive captured digits onto the bus in the order the digits were received.
