David I. August, Neil Vachharajani, and Matthew J. Bridges
United States Patent Number 9,128,750, September 2015.

A system that supports multi-threaded transactions includes one or more processors configured to speculatively execute a first thread in a first transaction and speculatively execute a second thread concurrently with the first thread in a comparable transaction with respect to the first transaction. It further includes one or more memories coupled to the one or more processors, configured to provide the one or more processors with data storage. An uncommitted value written by the first thread while executing in the first transaction is visible to the second thread executing in the comparable transaction.
