No, Ronbo. The 8088 microprocessor has 16-bit registers, 16-bit internal data bus and 20-bit address bus, which allows the processor address up to 1 MB of memory. The 8088 uses the same segmented memory addressing as the 8086: the processor can address 64 KB of memory directly, and to address more than 64 KB of memory the CPU has to break the update into a few parts - update up to 64 KB of memory, change segment register, update another block of memory, update segment register again, and so on.
