RAM de vídeo

video RAM RAM de vídeo

Um tipo especial de RAM dinâmica usada nas aplicações de vídeo de alta velocidade. A RAM de vídeo reserva pinos separados para o processador e os circuitos de vídeo, fornecendo ao circuito de vídeo uma "porta secreta" para a RAM de vídeo. Essa porta permite que os circuitos de vídeo acessem a memória bit a bit (serialmente), o que é mais apropriado quando se transferem pixels para a tela do que o acesso paralelo propiciado pela DRAM convencional. Acrônimo: VRAM. Pesquise também dynamic RAM (RAM dinâmica).
