We describe a fault-tolerant memory for an error-corrected logical qubit based on silicon double quantum dot physical qubits. Our design accounts for constraints imposed by supporting classical electronics. A significant consequence of the constraints is to add error-prone idle steps for the physical qubits. Even using a schedule with provably minimum idle time, for our noise model and choice of error-correction code, we find that these additional idles negate any benefits of error correction. Using additional qubit operations, we can greatly suppress idle-induced errors, making error correction beneficial, provided the qubit operations achieve an error rate less than $2 \times 10^{-5}$. We discuss other consequences of these constraints such as error-correction code choice and physical qubit operation speed. While our analysis is specific to this memory architecture, the methods we develop are general enough to apply to other architectures as well.
