Memory Types

• ESP32 Memory Blocks (Dynamic IRAM-DRAM Split)

IRAM (Instruction RAM)

• ESP-IDF allocates part of the Internal SRAM0 region for instruction RAM. 
The region is defined in ESP32 Technical Reference Manual > System and Memory > Embedded Memory 

DRAM (Data RAM)

• Non-constant static data (.data) and zero-initialized data (.bss) is placed by the linker into Internal SRAM as data memory. 
The remaining space in this region is used for the runtime heap.
