what is made of nand flash chip
时间: 2024-06-03 18:06:56 浏览: 11
A NAND flash chip is made of a series of memory cells, each consisting of a floating gate transistor and a control gate transistor. These cells are arranged in a grid-like pattern and connected to a series of word lines and bit lines. The floating gate transistor stores a charge that represents a binary value (0 or 1), while the control gate transistor controls the flow of electrons to and from the floating gate. The entire chip is typically housed in a small plastic or metal casing with electrical contacts for connection to a circuit board.

what is the code of deep learning momentum
The code for implementing momentum in deep learning depends on the specific deep learning framework you are using. However, in general, momentum is implemented by adding a fraction of the previous update to the current update during stochastic gradient descent optimization. Here is an example code snippet in Python using the Keras deep learning library:
```
from keras.optimizers import SGD
sgd = SGD(lr=0.01, momentum=0.9)
model.compile(loss='categorical_crossentropy', optimizer=sgd)
```
In this example, the momentum parameter is set to 0.9, which means that 90% of the previous update is added to the current update. This helps the optimizer converge faster and avoid getting stuck in local minima.
What is the purpose of TCP fast retransmission
The purpose of TCP fast retransmission is to improve the reliability and performance of data transmission over a network. When a TCP sender detects the loss of a packet, it will typically wait for a certain period of time before retransmitting the packet. With fast retransmission, however, the sender can quickly detect that a packet has been lost by receiving duplicate acknowledgments from the receiver. When the sender receives three duplicate acknowledgments for the same packet, it assumes that the packet has been lost and immediately retransmits it. This helps to reduce the overall delay and improve the throughput of the network by avoiding unnecessary timeouts and retransmissions.
