A portable memory storage device is disclosed where access to information on the device is granted only upon proper biometric authentication of a user. The device includes a controller, a non-volatile memory which may be a flash memory, and a biometric scanner system for controlling access to the information within the non-volatile memory. Each of the controller, non-volatile memory and biometric scanner system may be mounted in a base of the portable device, with the biometric system having an exposed surface on a top portion of the base for accepting biometric data such as a fingerprint. A cover is provided which includes a USB connector capable of mating within a USB port of the host device to establish communications between the portable and host devices. The cover also covers the exposed portion of the biometric scanner to protect the sensor when the portable memory storage device is not in use.

An interleaver for any modem or transmitter which transmits digital data. The interleaver eliminates the iterative divide step of a first prior art method to calculate the final depth of each block and the divide followed by a multiply step of a second prior art method. This is done by calculating the minimum depth, i.e., number of rows, for each 2-D block of data using a divide step and retaining the remainder. The remainder is used to determine how many blocks get an extra row when the burst length and width of each row precludes all blocks from having the same number of rows.
