Abstract
An address generator for a solid state disk drive device includes a hardware multiplier logic circuit dedicated to computation of the address by multiplying a lock size by a logical block number, to obtain the start address for a memory array read or write operation. The dedicated multiplier circuit advantageously provides very quick computation of these relatively large numbers, which typically involves a 32 bit by 16 bit multiplication. The multiplier includes a shift register initially holding the logical block number which is shifted a particular number of times, the number of shift pulses representing a value of the block length. The output of the shift register is the desired address.
