The Flash memory provides nonvolatile storage for code and data. The Flash memory is in-system programmable.

The SRAM (static RAM) can be used for both storage of data and execution of code and is split into two 4-KB blocks and two 6-KB blocks. Retention of the RAM contents in standby mode can be enabled or disabled individually for each block to minimize power consumption. In addition, if flash cache is disabled, the 8-KB cache can be used as a general-purpose RAM.

The ROM provides preprogrammed embedded TI-RTOS kernel, Driverlib, and lower layer protocol stack software ( Bluetooth low energy Controller). It also contains a bootloader that can be used to reprogram the device using SPI or UART. For CC2640R2Fxxx devices, the ROM contains Bluetooth 4.2 low energy host- and controller software libraries, leaving more of the flash memory available for the customer application.
