psp memory chip

MCS-51 Microcontroller in the physical structure has four storage space: 1. In-chip program memory2. Off-chip program memory3. In-chip data storage4. Off-chip data storage But logically, from the user's point of view, 8051 Single-Chip Microcomputer has three storage spaces:

a method of measuring memory chip with multimeter In the motherboard and memory data pins are 64, d0-d63, in order to protect the memory of the data bits, in the d0-d63 of these 64 bits of data are added a resistor with a small resistance to the current limiting effect. The main principle of the tester is to use the p

Let's talk about the memory Compilation Method in the computer today. For the computer's internal chip, People split it by bit. Let's take the following chip for example: Memory preparation There are 8x4 = 32 squares in the picture, that is, 32 bits. The following four lines are data lines used to retrieve data fro

control, write control, and chip selector . To write the data to the slice, first select the slice, then send out a write signal, switch clash, and the transmitted data (charge) into the film. If you want to read, select the slice first, then send out a read signal, the switch is closed, the data is sent out. Note in Figure 4, the read and write letters are also connected to another memory, but because the

Intel may strip out its memory and communication chip Division In May 18, chip industry analysts said intel may gradually strip its flash and communications business units in the next few months, and follow the example of its rival amd to cut spending, which is the main reason for the divestiture plan. At the same time, analysts also pointed out that e

NetEase Science and technology news Beijing time January 23 according to foreign web site reports, the Friday Munich Administrative Court spokeswoman Inglid Keps (Ingrid kaps) confirmed that the memory chip maker Dream Tatsu has filed for bankruptcy, distance to accept a hundreds of millions of Euro rescue loan scheme only one months. The court did not disclose more details. The headquarters of the company
