Abstract: A DRAM-compatible nonvolatile memory includes a FLASH memory and a logic controller. The logical controller accepts conventional DRAM command protocol and accepts data and addresses from DRAM data and address buses, respectively. The logic controller responds to repeated CAS-before-RAS signals and a write enable signal to initiate block erases and writes to the FLASH memory. The nonvolatile, DRAM-compatible memory is incorporated in a package having the same pin structure as a conventional DRAM package, such that the nonvolatile, DRAM-compatible memory can be mounted in a DRAM mount, such as a socket. Because the nonvolatile, DRAM-compatible memory can share common data, address, and command lines with conventional DRAMs, a single memory card can be produced containing both conventional DRAMs and the nonvolatile, DRAM-compatible memories.

Abstract: An implement attachment for the front end of a tractor comprises a tractor frame having transporting wheels and a frame device fixedly carried by the tractor frame, which extends parallel to the direction of transport. The frame device projects forwardly beyond the front end of the tractor. An actuating linkage movably carried by the tractor and also projects forwardly thereof and in combination with the frame device carries a three point hitch, one of the three points being on the linkage and the other two being on the frame device. The two hitch points are horizontally spaced transversely of the tractor and the one hitch point is disposed above such two hitch points. A conventional three point hitch can be connected to the three hitch points and manipulated by means of the actuating linkage.
