There are a number of ways to express the capacity of memory chips. Chip manufacturers specify the size of the chip in bits, and also in bytes. Bottom line is that a byte contains 8 bits. This means that 8 bits is one byte. The figure in bits sounds much better than the figure in bytes as the figure in bits is bigger. To give an idea on how many stitches a chip can hold: the minumum number of bytes required to store a single stitch is 2. On top of that there is a certain overhead which is not the same for all embroidery machines. This overhead consists of directory information, color changes etc. The table below shows the capacity of the various chips both in bytes and in bits. |
