WebOf course they talk about some SOFT IP-Core PSRAM controller for an external chip, classic stuff. But not a single word about how to instantiate, or access, or infer anything about the promised internal 64 Mb PSRAM. All I'm left with right now is the BSRAM and SSRAM, but of course I'll run out of these quite quickly if I try to use them as my ...

It is fabricated using the high-performance … WebDec 23, 2024 · PSRAM is an additional external 4 MB RAM that is present in some ESP32 modules: ESP32-WROVER-B ESP32-WROVER-I The ESP32 communicates with the PSRAM by the SPI protocol. This is why it is also called SPI RAM. The 3rd SPI bus of the ESP32 is used to communicate with the flash memory (which contains the program) and with the … WebMay 8, 2024 · PSRAM is an interesting blend of technologies. The core memory is a dynamic RAM with built in control/refresh logic. The exposed interface looks like a static RAM with Quad or Octal SPI control lines. All of the DRAM refresh details are taken care of by the internal logic. One example is an AP Memory APS6408L-OBM-BA. Figure 3. fifth scale degree
