The Volatile Memory Test (VMT) controls and monitors the test, initialization, and data integrity checking functions of the various internal memories in the device.

Each SRAM has digital logic surrounding it, known as SRAM Support Hardware (SSH). The SSH is a hardware block that controls the error detection and correction, Memory Built-In-Self-Test (MBIST) of internal memories. Each SSH block provides a unified interface for controlling its various functions. There are multiple such SSH instances, each of which controls one or more of the different internal memories. The VMT provides register interfaces to configure and control these various memory controllers.
