GHH and ZHH Package(s) Memory Map

The GHH and ZHH packages feature 21 address bits representing 2M-byte linear address for asynchronous

memories per CE space. Due to address row/column multiplexing, address reach for SDRAM devices is 4M

bytes for each CE space. The largest SDRAM device that can be used with the 5503 in a GHH and ZHH

package is 128M-bit SDRAM.

Memory Blocks

† Address shown represents the first byte address in each block.

‡ Dual-access RAM (DARAM): two accesses per cycle per block, 8 blocks of 8K bytes.

§ External memory spaces are selected by the chip-enable signal shown (CE[0:3]). Supported memory types include: asynchronous static

RAM (SRAM) and synchronous DRAM (SDRAM).

¶ The minus 64K bytes consists of 32K-byte DARAM/HPI access and 32K-byte DARAM.

# Read-only memory (ROM): one access every two cycles.
