In tale chip, secondo una codifica precisamente specificata, sono raccolti i dati dei vari parametri necessari al buon funzionamento di quel modulo di memoria (per esempio, il voltaggio d'alimentazione e la frequenza di clock). All'avvio del computer, durante l'iniziale fase del POST, tali dati possono essere letti dal BIOS per automatizzare la configurazione del sistema, permettendo la gestione ottimale della memoria installata e la successiva stabilit\u00E0 operativa. Le caratteristiche e il protocollo di codifica dei dati usati per il SPD sono specificati in standard tecnici (p.e. la serie SPD4_01_x), elaborati dall'organismo di standardizzazione JEDEC. Storicamente, il SPD costituisce il miglioramento evolutivo del Parallel Presence Detect (PPD), un precedente metodo di configurazione automatica della memoria RAM. Tale precedente metodo, adottato principalmente per i moduli di tipo SIMM, non forniva una flessibilit\u00E0 sufficiente a supportare le nuove tecnologie di memoria (come le SDRAM), finendo quindi per essere sostituito dal SPD."@it . .
