6. 4MX16 BIT SYNCHRONOUS DRAM (SDRAM)
6.1 General Description
The EM638165 SDRAM is a high-speed CMOS synchronous DRAM containing 64 Mbits. It
is internally configured as 4 Banks of 1M word x 16 DRAM with a synchronous interface (all
signals are registered on the positive edge of the clock signal, CLK). 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 EM638165 provides for programmable Read or Write burst lengths of 1, 2, 4,
8, or full page, with a burst termination option. 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. By having a programmable
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 and
particularly well suited to high performance PC applications.

8 internally. The MX25L512 feature a serial peripheral interface and software protocol
allowing operation on a simple 3-wire bus. The three bus signals are a clock input (SCLK), a
serial data input (SI), and a serial data output (SO). SPI access to the device is enabled by CS#
input. The MX25L512 provide sequential read operation on whole chip. After program/erase
command is issued, auto program/ erase algorithms which program/ erase and verify the
specified page or sector/block locations will be executed. Program command is executed on
page (256 bytes) basis, and erase command is executes on chip or sector (4K-bytes). To
provide user with ease of interface, a status register is included to indicate the status of the
chip. The status read
command can be issued to detect completion status of a program or erase operation via WIP
bit. When the device is not in operation and CS# is high, it is put in standby mode and draws
less than 10uA DC current. The MX25L512 utilize MXIC's proprietary memory cell, which
reliably stores memory contents even after 100,000 program and erase cycles.
