# 1.10 Memory Driver Asynchronous - NVM SST26 Read Write

This example application shows how to use the Memory driver in asynchronous mode to perform block operations on the NVM and the SST26 media’s.

## Description

- Uses multi instances of the Memory driver to communicate with the NVM and the SST26 Flash memories in asynchronous mode of operation in Bare-Metal environment
- Performs block Erase/Write/Read operations on both the media’s
- Consists of five tasks which are called through the SYS_Tasks() routine in Bare-Metal environment
  1. DRV_MEMORY_0_Tasks():
     - Manages the state machine of the Memory driver instance 0
  2. DRV_MEMORY_1_Tasks():
     - Manages the state machine of the Memory driver instance 1
  3. APP_SST26_Tasks():
     - Performs operations on the SST26 QSPI/SQI Flash memory
  4. APP_NVM_Tasks():
     - Performs operations on the NVM
  5. APP_MONITOR_Tasks():
     - Monitors the state of above two Tasks
