Transmission buffer apparatus and methods configured to minimize the storage requirements for transmission/retransmission of data by allocating retransmission data to two or more types of storage. In one embodiment, RAM usage in a RAM-limited embedded device is minimized by storing only a reference or pointer to ROM- or Flash-sourced within the retransmission buffer (e.g., RAM), thereby reducing the storage burden on the buffer. For example, web pages having largely non-volatile components can be stored in ROM or Flash, while only the dynamic or volatile portions are stored in RAM. Apparatus and methods for implementing an exemplary serial-to-Ethernet interface are disclosed, as well as use of Flash or ROM to store configuration data in the form of e.g., a web page image. A circular buffer approach implementing the aforementioned methodologies is also described.
