I know this is an old question, but these answers didn't work for me, and I had EXACTLY this problem. What DID work was resetting my calculator RAM through the memory command and then resetting defaults through the memory command. Everything is peachy now.

If you get Memory Error its meaninig that memory is insufficient to perform the instruction or function. You must delete items from memory
before executing the instruction or function.
Recursive problems return this error; for example,
graphing the equation Y1=Y1.
Branching out of an If/Then, For(, While, or Repeat
loop with a Goto also can return this error because
the End statement that terminates the loop is never
reached.

I'm not sure, but it probably gives the error because one of the values you entered isn't valid. It's too big or too small.

For more information, look here:

If this doesn't solve the problem, please let me know.

SOURCE: I'm receiving the message ERR: DATA TYPE 1:Quit

Hi,
If you want to know exactly where there is an error press the 2:Goto and the cursor will take you there. The message is clear: Some data you input is not of the right type.
Since you do not say much about what it is you are trying to do statistics on, I for one cannot guess. I suggest you press the STAT key and select 5:SetUpEditor then press ENTER.

Hope it helps.
Thank you for using FixYa.

SOURCE: When graphing says ERR: INVALID DIM 1:Quit

You have two lists that don't agree in length.

Solution 1 (easy)

Press [y=] and look at the top line - one of your Plots is highlighted.
Move the arrow to the highlighted one, press enter to get it un-highlighted.

Solution 2 (permanent)

Press [STAT] - EDIT: [1] to edit your lists. Go to the bottom of the lists and see which one is the longest. Delete (DELETE, not clear) the "extra" entries in the longest list until all lists are the same length.

On my TI-84 Plus: Once I go to STAT Edit it asks me to name the tables, and when I try to put in L1, it gives me a message saying ERR: ARCHIVED. What do I do??

You already have a list L1 archived in memory.

You have two choices. You can either choose another name or you can unarchive the existing L1. To unarchive a list, press 2ND [MEM] 2 4 then use the arrow keys to move the highlight to the line containing L1 (there should be an asterisk "*" in front of the name). Press ENTER and the asterisk should disappear. Press 2ND [QUIT] to return to the home screen.

When i try to look at the graph i've given the expression in "Y=", the calculator wrote on the screen "ERR:DIM MISMATCH" How can I manage to look at my graph then ? What's the preblem ?

Hello,
Reset the memory of the calculator and draw your graphs again.
To reset memory
Press [2nd][MEM][3:Reset][2:Reset][ENTER].
Since this procedure resets the screen contrast to default settings, you may have to adjust it.
To adjust contrast
Press [2nd] key and release it.
Press and hold [UpArrow] to darken or [DownArrow] to lighten contrast.

Hope it helps.

When I try to graph it says "ERR: INVALID DIM". How do I get rid of that, so I may graph my equations?

Hello,

1. TurnOff the STATPLOTS by pressing [2nd][STAT PLOT][4:PlotsOFF]. Command echoes on the home screen. Press ENTER. Screen displays Done

2. Run the command ClrAllLists to clear the lists. Press [2nd][Catalog] Scroll down till you reach the ClrAllLists command. Highlight and press [ENTER]. Command echoes on main screen, press [ENTER] to execute it. Screen displays Done

3. Make sure you are drawing the right type of graph. To check that press [MODE], scroll down to 4th line to highlight Func and press ENTER, if you are drawing y=f(x) functions. The others are PARametric, POLar, SEQuence.

The above procedures (the first two) are likely to solve your problem. In case that does not work reset the RAM.

Press [2nd][MEM][7:Reset][1:All ram][2:Reset] [ENTER]. Screen shows RAM cleared. Clear the screen and use [Y=] to enter the functions you want to graph.
Hope it helps.

When i press most buttons it gives me the message ERR:MEMORY i cant access memory so i cant reset ram or delete . also i can not connect to my cpu it says TI-84 plus Silver Edition detected, but couldn't...

From the TI knowledge base and FAQ

How do I correct ERR: MEMORY on a TI-83 family or TI-84 Plus family graphing calculator?

An ERR: MEMORY is given when there is not enough memory to perform the instruction or function. To increase available memory by deleting the contents of any variable (real or complex number, list, matrix, Y= variable, program, Apps, AppVars, picture, graph database, or string), follow these steps. • Press [2nd] [MEM] to display the MEMORY menu.
• Press 2: Mem Mgmt/Del.
• Select a variable or data that needs to be deleted and press [ENTER].
• Use the arrow keys to move the cursor next to the item, and then press [DEL]. The variable or data should now be deleted from the memory.
When deleting programs or Apps, a message asking for confirmation will appear. Select 2:Yes to continue. To leave any variable screen without deleting anything, press [2nd] [MODE].
Notes:
With the exemption of programs and Apps, no warning will be given to verify the deletion.Some system variables, such as the last-answer variable Ans and the statistical variable RegEQ, cannot be deleted.

Hope it helps.

"Err: Data Type" - Not Allowing Me to Graph

First, turn it on. Once the calculator is on, press the "2ND" key (I believe it is a blue key in the ti-84 plus silver edition). Now press the plus key (+). A little above that key, you should see the word "mem." When you see the screen titled MEMORY, move the cursor all the way down to the option that says "Reset." From here, you can choose to reset either the RAM memory, or the factory settings. The factory settings are the "Defaults" option. I hope this helps.
