Beckham missed the opportunity to play for the Galaxy against his former club last summer as he was sidelined with an Achilles injury which saw him miss the World Cup in South Africa.
But the Londoner says he is relishing the prospect of meeting Madrid on the Spanish side's current tour of the United States, despite a shoulder problem.
"I have good memories of my time with Madrid," he said.
"I wasn't able to play last year, but I don't want to miss it this time - it will be a special game.
"I have a shoulder problem, but it feels better all the time and I have a week to prepare for the game against Madrid."
"Ronaldo is a phenomenon and one of the best players (in the world). I look forward to seeing him," he said.
Beckham was signed for Madrid by Florentino Perez in 2003, but the construction magnate stepped down two years later before taking over again in 2009, when the Englishman had already moved on.
"If Florentino had stayed, I am sure I would have retired at Real Madrid," Beckham said.
