Methods, algorithms, architectures, circuits, and/or systems for dynamically allocating memory for storing parametric data in optical transceivers are disclosed. The optical transceiver can include an optical receiver configured to receive optical data; an optical transmitter configured to transmit optical data; a microprocessor configured to access data for each of a plurality of parameters that are related to operation of at least one of the optical receiver and the optical transmitter; one or more memories configured to store the data at a plurality of locations that are dynamically allocated by the microprocessor; and an interface configured to receive a request for data for one or more of the parameters from a host and provide the data in response to the request. In the present disclosure, the host is unaware of the locations at which the parametric data are stored.
