The 512Mb SDRAM is a high speed CMOS, dynamic random-access memory
designed to operate in either 3.3V Vdd/Vddqor 2.5V Vdd/Vddqmemory
systems, depending on the DRAM option. Internally configured as a
quad-bank DRAM with a synchronous interface.
The 512Mb SDRAM (536,870,912 bits) includes an AUTO REFRESH MODE,
and a power-saving, power-downmode. All signals are registered on
the positive edge of the clock signal, CLK. All inputs and outputs
are LVTTL compatible.
The 512Mb SDRAM has the ability to synchronously burst data at a
high data rate with automatic column-address generation, the
ability to interleave between internal banks to hide precharge time
and the capability to randomly change column addresses on each
clock cycle during burst access
.A self-timed row precharge initiated at the end of the burst
sequence is available with the AUTO PRECHARGE functionenabled.
Precharge one bank while accessing one of the other three banks
will hide the precharge cycles and provide seamless, high-speed,
random-access operation.
SDRAM read and write accesses are burst oriented starting at a
selected location and continuing for a programmed number of
locations in a programmed sequence. The registration of an ACTIVE
command begins accesses, followed by a READ or WRITE command. The
ACTIVE command in conjunction with address bits registered are used
to select the bank and row to be accessed (BA0, BA1 select the
bank; A0-A12 select the row). The READ or WRITE commands in
conjunction with address bits registered are used to select the
starting column location for the burst access.
Programmable READ or WRITE burst lengths consist of 1, 2, 4 and 8
locations or full page, with a burst terminate option
