Memory
The Zynq 7Z045 Mini-Module Plus Development Board is populated with both high-speed RAM
and non-volatile ROM to support various types of applications. Each development board has five
memory interfaces:
1. DDR3: 1GB x32 DDR3 SDRAM
2. 32 MB QSPI Flash
3. 256 MB Parallel Flash x16
4. 8 KB I

Micron
DDR3 SDRAM devices, part number
MT41K256M16HA-125E:E
, make up the 1
GB x32 SDRAM memory interface. Each device provides 512 MB of memory on a single IC
and is organized as 32 Megabits x 16 x 8 banks. The device has an operating voltage of 1.5 V
and the interface is JEDEC Standard SSTL_15 (Class I for unidirectional signals, Class II for
bidirectional signals). The -125E speed grade supports 1.25 ns cycle times with 11 clock read
latency (DDR3-1600). The following figures show a high-level block diagram of the DDR3
SDRAM interface on the development board
