A method and system for garbage collection are provided. A memory allocation request is received for an object. An object identifier is generated for the object. A first memory location is allocated to the object. A translation table is generated storing a map of the object identifier and the first memory location. A data structure is generated for the object. A mark flag is set based on the number of references of the object. Data stored in the first memory location is moved to a second memory location based upon the value of the mark flag. The data is deleted from the first memory location based upon a value of the mark flag.
