"Memoria" was written by Cris Morena and Carlos Nilson, the usual composers of Erreway's songs. The two has written almost all songs by Erreway, which were recorded for their previous albums Señales (2002) and Tiempo (2003). "Memoria" was chosen to be a titular song for their third album Memoria, which was described as their "most mature album". It features all band members — Benjamín Rojas, Felipe Colombo, Camila Bordonaba and Luisana Lopilato — as lead vocals, with Bordonaba singing Lopilato's part after she left the band in 2007. "Memoria" was the first song on Memoria, and the first and the only official single from the album. In 2007 it was confirmed the song would be re–recorded for Erreway's fourth album Vuelvo, but it is unknown if it would be released as a single.
