The Ayama 10000A device consists of M × 72-bit (M = 256K for CYNSE10512A, 128K for CYNSE10256A, 64K for
CYNSE10128A) storage cells referred to as data bits. There is also a mask cell corresponding to each data cell. A database entry
includes both the data and mask cells. Figure 4-1 shows the four possible table width sizes of the data and mask cells and the
maximum possible table depth for each width.
The Ayama 10000A can be configured to contain tables of different widths in one device up to a maximum equal to
512K/256K/128K 72-bit entries. For example, a single Ayama 10000A device can have both a 5-Tuple Flow table and an IPv6
forwarding table. Figure 4-2 shows a sample configuration of multiple table widths in a CYNSE10512A device.
