# SRAM example
## Overview

SMA example project shows performance of reading and writing data in internal or external SRAM memory.

## Board Setting

External SRAM module is required. The tested SRAM is IS62WV51216EBLL45TLI.

HPM6300 series has only 8 address lines in non multiplexing mode of address lines and data lines, so the high address lines of IS62WV51216EBLL45TLI must be connected to GND.


## Running the example

When the project runs correctly, and the serial port terminal will output the following information:
```
sram example
comparison test: from 0x48000000 to 0x48001000
**  u32 comparison succeeded
**  u16 comparison succeeded
**  u8 comparison succeeded
```

## Hint
When SRAM interface is used to access external devices, such as FPGA, SRAM address space should be configured as non-cacheable.
