Zeus 2.5-Inch ATA Solid State Drive
SSD Control Block
The control block of the Zeus SSD is comprised of three integrated components:
FPGA Controller
The Field Programmable Gate Array (FPGA) controller Zeus SSD provides the ATA interface to the
host, and the IDE interface to the local flash memory installed in the drive. The integrated DMA
controller interfaces with system memory to facilitate data transfer between the host and the local
flash memory in the SSD.
RISC Microcontroller
An integrated RISC microcontroller is responsible for initiating and controlling all activity within the
Zeus ATA controller. The microcontroller features more than 1 Mbit of on-chip SRAM and a wide
range of peripheral functions, with 8 Mbits of flash memory into a single compact 120-BGA package.
The embedded microcontroller is a high-performance processor with a high-density instruction set
with very low power consumption. In addition, a large number of internally banked registers provide
very fast exception handling, making it ideal for real-time application control requirements. The 8-
level priority-vectored interrupt controller, together with the Peripheral Data Controller, significantly
enhance the real-time performance of the SSD.
The flash memory controller architecture requires only minimal external component support. The
flash controller can interface with a wide range of compatible flash memory devices from other
manufacturers. Features of the flash memory controller include:
NAND SLC Flash Memory
The local storage subsystem uses Single-Level Cell (SLC) NAND, non-volatile flash memory that has
only two states and one bit of stored data. The SLC NAND flash control logic on the SSD is able to
conserve energy when managing the electrical charge during operations.
