This cost-effective memory card has a very simple design, containing only the memory element itself (without any drive/controller circuitry). A simple plastic substrate carries 1 (or 2) Standard NAND FLASH memory chip(s), which is (are) directly bonded to the back side of the contact surface. Remarkable in the mid-90s were the very small dimensions of the card of only 37.0 x 45.0 x 0.76 mm, which resulted in the wide-spread use of the SmartMedia Card in the consumer area, e.g. in DSC, MP3 players, dictating machines and so on. Initially, the card also existed as a 5-volt variant (with a beveled upper left corner). Today, only the 3 (or 3.3)-volt variant is used. These cards are available with memory capacities of 8, 16, 32, 64 and 128 Mbytes. Meanwhile, the advanced state of standardization has eliminated the initial compatibility problems that occurred when new cards with higher capacities became available.
