Quantum repeater architectures based on absorptive rare-earth-ion photonic memories offer a promising route toward highly multiplexed quantum networking, but integrating spectrally matched photon sources and quantum memories within a common platform remains a major challenge. Here we demonstrate an integrated photonic architecture for telecom photon-memory entanglement generation based on dual silicon-carbide microring resonators. One resonator operates as an entangled photon-pair source, while the other functions as a cavity-enhanced atomic-frequency-comb quantum memory. The memory resonator achieves an ensemble cooperativity of 1.9 and is intrinsically spectrally matched to the photon source, enabling storage of entangled telecom photons without spectral modification. We generate and verify photon-memory entanglement with a single-pair interference visibility of 88.1 $\pm$ 10.6%. By exploiting the multimode capacity of the memory, we demonstrate high-dimensional photon-memory qudit entanglement spanning up to 63 temporal modes, leading to a maximum photon information efficiency of 5.1 Ebits per detected photon and a peak on-chip photon-memory entanglement rate of 5.6 kEbits s$^{-1}$. These results establish the first integrated platform for photon-memory entanglement generation and provide a scalable route toward chip-scale quantum repeaters and memory-enabled quantum networks operating over telecommunications infrastructure.
