AbstractA very small computer memory card is densely packed with a large number of flash EEPROM integrated circuit chips. A computer memory system provides for the ability to removably connect one or more of such cards with a common controller circuit that interfaces between the memory cards and a standard computer system bus. Alternately, each card can be provided with the necessary controller circuitry and thus is connectable directly to the computer system bus. An electronic system is described for a memory system and its controller within a single memory card. In a preferred physical arrangement, the cards utilize a main circuit board with a plurality of sub-boards attached thereto on both sides, each sub-board carrying several integrated circuit chips.
