20.1
The H8S/2138, H8S/2134, and H8S/2133 have 4 kbytes of on-chip high-speed static RAM, and
the H8S/2137, H8S/2132, and H8S/2130 have 2 kbytes. The on-chip RAM is connected to the
CPU by a 16-bit data bus, enabling both byte data and word data to be accessed in one state. 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).

Figure 20.1 shows a block diagram of the on-chip RAM.
