1.3.1. On-chip SRAM memory
The GD32VF103 series of devices contain up to 32 KB of on-chip SRAM which address starts
at 0x2000 0000. It supports byte, half-word (16 bits), and word (32 bits) accesses.
1.3.2. On-chip flash memory overview
The devices provide high density on-chip flash memory, which is organized as follows:
 Up to 128KB of main flash memory.
 Up to 18KB of information blocks for the boot loader.
 Option bytes to configure the device.
Refer to Flash memory controller (FMC) Chapter for more details.
