Features of the static random-access memory (SRAM) include:
• On-chip, 8-Kbyte static random-access memory (SRAM)
• Fixed address space
• Byte, half-word (16-bit), or word (32-bit) read/write accesses
• One clock per access (including bytes, half-words, and words)
• Supervisor or user mode access
• Standby power supply switch to support an external power supply
8.3 Modes of Operation
Access to the SRAM is not restricted in any way. The array can be
accessed in all supervisor and user modes.
