Innoventions RAMCHECK
Portable Memory Tester

• Saves time by quickly testing memory, not inside computer
• Saves money by checking and identifying all expensive inventory of memory modules
• Has a 184-MHz test engine, parallel data access capability, and state-of-the-art timing circuitry available in expensive desktop testers (184MHz test capability translates to 184x2=368MHz DDR)
• Modular design and variety of existing and planned adapters provide broad coverage of today's and future memory technologies
• Fully and quickly test PC-133 SDRAM technology at actual clock speeds
• Automatic tests provide full support for SDRAM/EDO/FPM without the need for special setup
• Upgrade easily with FLASH EPROMs via the Internet
• Complete support for Serial Presence Detect (SPD) data, including reading, editing, and programming
• Use as a stand alone tester, or connected to a PC via the built-in PC serial interface
• Snap-in expansion ports for a variety of add-on adapters
• Zero-Insertion-Force socket for testing 168-pin DIMMs
• 100-240 VAC 50/60 Hz Universal Switching Power Supply included

Highly modular and user friendly, the RAMCHECK redefines the capabilities of an affordable and portable memory tester. The newly designed 184-MHz test engine and scaleable data interface provides faster tests and gives you a higher resolution of timing measurements. RAMCHECK's architecture has been optimized to better support the memory devices of today and tomorrow. Optional RAMCHECK adapters support numerous types of memory devices, including SO DIMMs, old SIMMs, individual chips, and more. Its 184MHz test capability translates to 184x2=368MHz DDR, which is more than adequate for today's 266MHz DDR devices!

Using Innovention's enhanced proprietary algorithms, RAMCHECK runs a thorough test on today's SDRAM/EDO/FPM memory modules, testing every memory cell. All chips are tested simultaneously to yield a faster test and to enable the instrument to detect errors that are caused by interference among the chips on the module. RAMCHECK is not merely a go/no-go tester. In fact, it explicitly identifies the faulty bits within a defective module, giving specific pin number information relating to the problem chip. While 100% accuracy in memory testing is technically impossible, RAMCHECK achieves a high degree of accuracy in detecting bad memory devices.

Pressing one button starts the fast BASIC test which automatically measures and displays the module size, Mode Type (SDRAM/EDO/FPM), Access Frequency (or Access Time/Cycle Time for non-SDRAM devices), Cycle Time measurement and more. The BASIC test checks for wiring and verifies that all memory cells are sound. The EXTENSIVE test automatically follows with Voltage Cycling and Voltage Bounce tests which verify the module performance under varying voltage conditions. The March Up/Down algorithm detects interference among cells. Various tests like Relative Refresh and Relative Spikes provide detailed insight into the quality of the tested module. Our proprietary Chip-Heat mode automatically warms the chips for temperature related speed measurement at the end of EXTENSIVE test. The AUTO-LOOP test provides the perfect burn-in means for your memory modules, as well as additional pattern testing.

RAMCHECK incorporates additional setup capabilities over our standard SIMCHECK II setups to satisfy the needs of even the most advanced and demanding engineers.

Just as you would expect, RAMCHECK can easily be upgraded and expanded to protect your investment. This goal was achieved using modern FLASH EPROM technology and a PC Windows companion program which allows you to download the firmware from the Innoventions Internet website or from a distribution diskette. RAMCHECK comes with a built-in serial interface and is packaged with all you need for an easy connection to the PC.

With its four expansion sockets, RAMCHECK is a highly expandable and modular tester. In addition to the add-on devices available, we are continuously developing more optional adapters to support future memory technologies.

RAMCHECK EASE OF USE

These actual screen images of RAMCHECK's display illustrate its power, ease of use, and versatility.

	Clear messages identify good and bad modules. Successful tests result in high pitch beeps, while errors sound low pitch signals.
	Scrollable error menus provide a graphic display of the error and its associated pin number.
	Address wiring errors are explicitly shown.
	Variations from the standard devices are clearly indicated.
	Structure information at the end of Basic Test indicates which control signals are used!
	A detailed Test Log including all the test results can be viewed after every test by simply pressing F4.

TEST PHASES

    RAMCHECK tests have been significantly enhanced over our previous generation, resulting in more support for today's memory devices, as well as added test results not available before.

	BASIC Test quickly checks all the wiring and all the memory cells. Speed shown here is 133MHz.
	EXTENSIVE Test includes many tests that give you more insight into the quality of your memory.
	AUTO LOOP Test checks the memory with endless changing patterns. It is also perfect for burn-in operation.

SETUP

	Menus for setup and other operations are clear and interactive.
	Graphic setup of timing parameters will please most advanced users.
	Detailed setup list keeps track of all (optional) changes you made to the default program.
