Abstract:
A memory component has a signaling interface, data input/output (I/O) circuitry, command/address (CA) circuitry and clock generation circuitry. The signaling interface includes an on-die terminated data I/O and an unterminated CA input. The data I/O circuitry is dedicated to sampling write data bits at the data I/O timed by a strobe signal and to transmitting read data bits timed by a first clock signal, each of the write and read data bits being valid for a bit time at the data I/O. The CA circuitry samples CA signals at the CA input timed by a second clock signal, the CA signals indicating read and write operations to be performed within the memory component. The clock generation circuitry generates the first clock signal with a phase that establishes alignment between a leading edge of the bit time for each read data bit and a respective transition of the second clock signal.
