The H8S/2626 and H8S/2623 have 12 kbytes of on-chip high-speed static RAM, the H8S/2625
and H8S/2622 have 8 kbytes, and the H8S/2624 and H8S/2621 have 4 kbytes. The RAM is
connected to the CPU by a 16-bit data bus, enabling one-state access by the CPU to both byte data
and word data. This makes it possible to perform fast word data transfer.
The on-chip RAM can be enabled or disabled by means of the RAM enable bit (RAME) in the
system control register (SYSCR).
