Abstract: A circuit for converting signals between a memory interface and a memory array is disclosed. The memory interface is not the same type as the memory array such that the signals between the interface and the array need to be synchronized and translated. The circuit includes an interface converter for shifting the logic levels of the signals between the memory interface and the memory array. Furthermore, the circuit has a translation block for translating and synchronizing the signals. In this respect signals between the memory array and the memory interface are synchronized and translated such that the memory array can be used with a memory interface of a different type.

Abstract: A PCMCIA compatible memory card having a serial communication interface is provided. The serial communication interface includes a controller, a serial transceiver, and a serial communication port. Coupled between the controller and the serial communication port, the transceiver enables the controller to send or receive data through the serial communication port. Nonvolatile memory on the card is accessible by the controller. A cable connects the serial communication port of the memory card to a serial communication port of an external host computer. The controller operates in accordance with commands received from the host computer through the serial communication port of the card for sending data read from memory of the card to the computer, writing data to memory of the card received from the computer, loading a file into memory of the card received from the computer, erasing data from memory of the card, or verifying data in memory on the card.
