Vinyl package ASIC controller chip itself of the logic is very simple, generally this control chip of flash card less powerful, or a single card or co-card using 32Mbit partition, the majority of cassette does not support the clock, archive support is not enough high, the top of the software development for these cassette by the restrictions of the hardware is almost all can not support a soft reset and cheat function, less power consumption (power consumption of D card at a level), low price.

Part of the archive memory flash card game archive file is stored SRAM chip for charging circuit, in general, less than the 512Mbit cassette all use the 2Mbit chip, while the the 512Mbit above (including 512Mbit) the cassette will be more than 4Mbit SRAM (XG2T512, special SMS is the archive core, so do not need too much capacity SRAM), SRAM powered by a 3V button battery, a lot of flash cards used in rechargeable battery, in order to avoid the battery power is exhausted, unable to provide sufficient electric power to the SRAM, resulting in the occurrence of the problem of lost files.

Addition, some cards there are other special features, the part of non-burning cassette must form, the special features part of the development of manufacturers in order to provide more selling points and features developed, the most important is the clock circuit part, the clock circuit mainly by the clock chip and crystal.

There must constitute a game backup area is still non-flash card, recently introduced a number of burning products have, the more representative is the EZ3, constitute the equivalent of 256Mbit burn cassette plus the 128Mbyte the U disk, which the 128Mbyte the memory chips used NAND type FLASH, thus providing a high-capacity low-cost game reserve storage solutions, of course, stored in the game can not be run directly, still need to extract it to a cassette SRAM area or region of NOR-type flash run
