Features
Overview
The EM6AB080 SDRAM is a high-speed CMOS
double data rate synchronous DRAM containing 512
Mbits. It is internally configured as a quad 16M x 8-bit
DRAM with a synchronous interface (all signals are
registered on the positive edge of the clock signal, CK).
Fast clock rate: 250/200MHz

Internal pipeline architecture
Four internal banks, 16M x 8-bit for each bank
Programmable Mode and Extended Mode registers

Read and write accesses to the SDRAM are burst
oriented; accesses start at a selected location and
continue for a programmed number of locations in a
programmed sequence. Accesses begin with the
registration of a BankActivate command which is then
followed by a Read or Write command. The EM6AB080
provides programmable Read or Write burst lengths of
2, 4, or 8. An auto precharge function may be enabled
to provide a self-timed row precharge that is initiated at
the end of the burst sequence. The refresh functions,
either Auto or Self Refresh are easy to use. In addition,
- Burst length: 2, 4, 8
- Burst Type: Sequential & Interleaved
Individual byte write mask control
DM Write Latency = 0
Auto Refresh and Self Refresh
8192 refresh cycles / 64ms

EM6AB080 features
programmable DLL option. By
having a programmable mode register and extended
mode register, the system can choose the most
suitable modes to maximize its performance. These
devices are well suited for applications requiring high
memory bandwidth, result in a device particularly well
suited to high performance main memory and graphics
applications.
