The IDTSA/LA is a 16,bit high-speed static RAM organized The IDTSA/LA is packaged in pin mil plastic DIP, pin. The 5V CMOS SRAM is organized as 2K x 8. The offers a reduced power standby low-power (LA) version also offers a battery backup data. The IDTSA/LA is a 16,bit high-speed static RAM organized as 2K x 8. It is fabricated using IDT’s high-perfor- mance, high-reliability CMOS technology.

I can view each byte of junk data the SRAM has been initialized with. Increase the current limit the LED’s or remove them, yeah its cool to see the data go by but useless and the problem in all likelihood will go away.
What speed grade are your RAM chips, and where did you get sgam Post as a guest Name. Home Questions Tags Users Unanswered. I have connected the outputs to 8 LEDs and tied all address inputs low.
What value is the LED current-limiting resistor? The SRAM chip does not appear to be damaged by this, as when power is cycled off and back on again it returns to working normally. So typically the output voltage of the IDT could be higher.
So I believe what is happening here is the IDT part is sourcing much more current and burning up much more power.
And be sure to use a separate resistor for each LED. At first everything works as expected.
I have observed this behavior with all 3 IDT chips I ordered.

I am building a memory module for an 8-bit computer, and am running into an issue. Eli Lorden 12 2. An LED’s IV curve is exponential, so if you give it a little more voltage, you get a lot more current. The chip is receiving 5V, which is within the tolerances listed on the datasheet.
