I suggest you read through the information at this link: http://www.ssa.gov/pubs/10035.html This Social Security publication suggests that as long as your spouse has documentation showing she is a legal resident alien, she can receive benefits from your wage earner's record.
There are a few other factors that could affect her entitlement to benefits from your wage earner's record, but they might or might not be present at the time of your death. For example, you would need to be fully insured (as regards Social Security benefit coverage) at your time of death--again the link above provides some useful information. Other factors that could change is Congressional revision of the Social Security statutes/programs to make the program means-tested, etc.

When is your wife eligible to apply for US citizenship? For people who are married to US citizens, the non-citizen spouse is eligible after being a permanent resident for three years. I always urge people to file as soon as they are eligible, unless there are criminal or other issues, and one reason is to protect their access to benefits in situations like yours. Permanent residence is easy to lose and offers limited rights, while citizenship offers much greater protection. If you have questions about the naturalization process, talk to an immigration attorney or check out some of the great resources available online--USCIS publishes a citizenship resource center here:Ask a similar question
